Building Master was created by Reinhard
I created a fresh installed VM with debian stable (jessie). There I cloned linuxcnc master.
Then I followed install recommendations from linuxcnc, which means, all dependencies are checked and installed.
in linuxcnc/debian directory I executed the command "./configure uspace rtai" and the following build (dpkg-buildpackage -b -uc) failed with this log:
dh_movefiles
dh_movefiles: debian/tmp//usr/lib/libuspace-rtai.so.0 not found (supposed to put it in linuxcnc-uspace-rtai)
tar: /usr/local/src/linuxcnc/debian/movelist: Funktion stat fehlgeschlagen: Datei oder Verzeichnis nicht gefunden
tar: Error is not recoverable: exiting now
tar: Das sieht nicht wie ein „tar“-Archiv aus.
tar: Beende mit Fehlerstatus aufgrund vorheriger Fehler
dh_movefiles: (cd debian/tmp >/dev/null ; tar --create --files-from=/usr/local/src/linuxcnc/debian/movelist --file -) | (cd debian/linuxcnc-uspace-rtai >/dev/null ;tar xpf -) returned exit code 2
debian/rules:61: recipe for target 'install' failed
make: *** [install] Error 2
dpkg-buildpackage: Fehler: Fehler-Exitstatus von fakeroot debian/rules binary war 2
Then I scanned the build log and there was no attempt to build linuxcnc-uspace-rtai
... but I found a libuspace-xenomai.so.0 in debian/tmp

Are there any recommendations, I might have missed?

If you are trying to make a deb for uspace, try:
./configure uspace

if you are trying to make a deb for rtai, try:
./configure rtai

duh! Should have known that :(
May be it will be helpful to add a vertial line between uspace and rtai

The uspace build fails a bit later:
cp --no-dereference ../lib/liblinuxcncini.so ../lib/libposemath.so ../lib/libnml.so ../lib/libuspace-xenomai.so ../lib/liblinuxcnchal.so ../lib/libcanterp.so ../lib/librs274.so /usr/local/src/linuxcnc/src/../debian/tmp/usr/lib
ldconfig /usr/local/src/linuxcnc/src/../debian/tmp/usr/lib
make[1]: ldconfig: Kommando nicht gefunden
Makefile:573: recipe for target 'install-kernel-indep' failed
make[1]: [install-kernel-indep] Error 127 (ignored)
ldconfig is installed and accessible, but only for root users.
The build should be executed as ordinary user - right?
So may be, adding a sudo in front of ldconfig could solve the problem?

I found the line in linuxcnc/src/Makefile - but as that file is generated, I don't know enuf to patch the right place.

ok - temporarily patching Makefile works, but other errors arise:
sudo ldconfig /usr/local/src/linuxcnc/src/../debian/tmp/usr/lib
ERROR: ld.so: object 'libfakeroot-sysv.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
I guess, later occurring link errors depend on this failure:

Note: 'ignored'
So there is some other error that you are not showing us i think.

I routinely do the following in a script on debian jessie uspace as a NON-root user:
cd $GIT_ROOT # my root for the git tree (linuxcnc-dev)
cd src
./configure --with-realtime=uspace --enable-build-documentation=html
cd ../debian
./configure uspace
cd ..
time debuild -i -us -uc -b >|1.log 2>|2.log

(I had to install the package for libxenomai-dev)

(you should not have to use sudo or patch the Makefile
for making package; bad things may happen with sudo
that will can have long-term affects)

after reading the configure script, you do not have to install libxenomai-dev if you configure as:
./configure uspace noauto

Are these errors possibly because your source directory is not owned by you?
I normally build in ~/linuxcnc-dev but it looks you started in a system directory:

ldconfig /usr/local/src/linuxcnc/src/../debian/tmp/usr/lib

I have to admit, that I'm a linux user only. Not a linux developer.
I'm able to follow build instructions, but I don't know anything about build systems (aside from Makefiles).

@PCW
I consider /usr/local as "my" sandbox, so any software package, that I have to compile, will be extracted to /usr/local/src/<pkg-name>
I never use my home-directory to build system/foreign packages.
If the package uses cmake, I built the package at /usr/local/build (a scratch directory which I created)
Other packages will be build inplace.

I don't own /usr/local/src but group permissions allow to create directories there. When I check out a source package, I do own the package root directory - in this case /usr/local/src/linuxcnc

@dgarret
a call to src/configure is not necessary, as the debian build process calls that script on its own with different arguments.
Your build command looks quite weired. I tried it and it did not work.
... and I don't have a debuild command

@all
I removed the linuxcnc root directory and restarted from scratch with this commands:
cd /usr/local/src
git clone git://git.linuxcnc.org/git/linuxcnc.git linuxcnc
cd linuxcnc/debian
./configure uspace
cd ..
dpkg-checkbuilddeps #// got empty output
dpkg-buildpackage -us -uc -b -tc 2>&1 | tee build-5.log

@dgarret
your recommendations from first reply where wrong.
In debian directory a ./configure uspace works, but a ./configure rtai fails.
A quick look at configure shows this:
Usage:
    $P uspace [noauto | rtai | rtai=packagename | xenomai] ...
        Build for a userspace realtime systems or simulator
...

So my variant ./configure uspace rtai was right ;)

As far as i know, you can not use rtai on 64 bit systems. From your logs you are using 64 bit kernel.

you are kidding, don't you?

I thought, that every system has already reached 64bit =:O
Ok, I'll check it

//edit says:
Looking at debian/configure line #88ff
# rtai-modules typically doesn't properly declare the architectures where
# it works, so hardcode it...
RTAI_DEV="$(apt-cache search -n rtai-modules | head -1 | awk '{print $1}')"
RTAI_ARCHITECTURE="i386 amd64"
if [ ! -z "$RTAI_DEV" ]; then
    RTAI_DEV="$RTAI_DEV [i386], $RTAI_DEV [amd64]"
fi
So there's amd64 ...
... but on debian stable there are no "rtai-modules" at all
More precise: there is no "rtai-modules" in no release under no section :(
