The problem is introduced by the change I made to be able to bisect
while we move syscall_nr.h from source dir to build dir (as said by
Richard):

4d6a835dea47 ("linux-user: introduce parameters to generate syscall_nr.h")

There is also a new problem introduced by:

5f29856b852d(" linux-user, configure: improve syscall_nr.h dependencies
checking")

that doesn't scan arch variant (it scans ppc64-linux-user but not
ppc64le-linux-user).

The best solution I can propose is to simply remove the piece of code
I've added in configure and let the user to do a "make clean" if the
build fails because of the move of syscall_nr.h from source dir to build
dir.

Any idea?

Thanks,
Laurent
