PowerPC section flag tidy

Browse Source 
has_tls_get_addr_call is no longer named correctly as the flag is
only set on finding a __tls_get_addr call without tlsld/tlsgd marker
relocations.

	* elf32-ppc.c (nomark_tls_get_addr): Rename from has_tls_get_addr_call
	throughout.
	* elf64-ppc.c (nomark_tls_get_addr): Likewise.
