	* elf/dl-reloc.c (allocate_static_tls): Rename to...
	(_dl_allocate_static_tls): ... this function.  No longer static.
	(CHECK_STATIC_TLS): Adjust.
	* sysdeps/generic/ldsodefs.h (_dl_allocate_static_tls): New prototype.
	* sysdeps/powerpc/powerpc32/dl-machine.h (__process_machine_rela):
	Add SYM_MAP argument.
	(elf_machine_rela): Adjust caller.  Declare SYM_MAP unconditionally.
	Check if SYM_MAP != NULL for R_PPC_DTPREL32.  Only handle 32-bit
	TLS relocs here.  #ifdef out relocs which never appear in
	.gnu.conflict section from dl-conflict.c processing.
	* sysdeps/powerpc/powerpc32/dl-machine.c (__process_machine_rela):
	Add SYM_MAP argument.  Handle 16-bit TLS relocs here.
