* sysdeps/powerpc/powerpc64/dl-machine.h (elf_machine_fixup_plt):

Browse Source 
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.
