This reminds me of a similar rpmbuild failure I ran into two months ago,
also involving symlinks: https://lkml.org/lkml/2014/12/22/177 . My
current theory is that there's something odd going on at the
intersection of rpmbuild, cp -l, and/or patch.

But, of course, replaying part of your rpmbuild output didn't trigger
this problem on a f20 system:
    $ cp -al vanilla-3.19 vanilla-3.19-git7
    $ cd vanilla-3.19-git7/
    $ cat [...]/patch-3.19-git7.xz | unxz | patch -p1 -F1 -s
    $ file tools/testing/selftests/powerpc/stringloops/memcmp_64.S
    tools/testing/selftests/powerpc/stringloops/memcmp_64.S: symbolic link to `../../../../../arch/powerpc/lib/memcmp_64.S'

Still all very puzzling...
