[Buildroot] [git commit] package/xenomai: ignore custom versions

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=26dc3587e39d1bbbb200a32135b62bdda71056b7
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

We can safely reference XENOMAI_SOURCE, even though it is defined later,
because BR_NO_CHECK_HASH_FOR is a recursively-expanded variable, so its
content is only evaluated when the variable is referenced.
