There's no PLT avoidance for __dirfd, so this introduces a regression on 
GNU/Linux.  dirfd was expanded inline there.

      590:       e8 00 00 00 00          callq  595 <fts_build+0x75>
                         591: R_X86_64_PLT32     __dirfd-0x4

I think this calls for a different solution.

Thanks,
Florian
