* 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.
