* sysdeps/powerpc/powerpc64/dl-machine.h (elf_machine_rela): Remove
special case for dl_rtld_map in R_PPC64_RELATIVE; it's harmless to
repeat it and avoids the test for the common case.
Clean up and fix calculations for TLS relocs.
* sysdeps/powerpc/powerpc64/dl-tls.h: Moved to ...
* sysdeps/powerpc/dl-tls.h: ... here.
(TLS_TP_OFFSET): New macro.
* sunrpc/svc_udp.c (svcudp_recv): Add a cast to last change.
