* sysdeps/powerpc/powerpc64/dl-machine.h (elf_machine_fixup_plt):
Don't use weak_extern for dl_rtld_map. Instead check only if [SHARED].
(elf_machine_rela): Clean up.
* sysdeps/powerpc/powerpc32/dl-machine.h (elf_machine_rela): Clean up.
PowerPC TLS support contributed by Paul Mackerras <paulus@samba.org>.
* sysdeps/powerpc/powerpc32/elf/configure.in: New file.
* sysdeps/powerpc/powerpc32/elf/configure: New generated file.
* elf/tls-macros.h [__powerpc__ && !__powerpc64__]
(TLS_LE, TLS_IE, TLS_LD, TLS_GD): Define them.
* sysdeps/powerpc/powerpc32/dl-machine.h (elf_machine_rela): Support
new relocs for TLS.
* sysdeps/powerpc/dl-tls.h (TLS_TP_OFFSET, TLS_DTV_OFFSET): Move these
macros out of [SHARED].
(TLS_TPREL_VALUE, TLS_DTPREL_VALUE): New macros.
* elf/elf.h: Define R_PPC_* relocs for TLS support.
Clean up R_PPC64_* macro definition comments.
