Subject: Move UNDEFWEAK_NO_DYNAMIC_RELOC to elf-bfd.h
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=62cd30f167be56e68cb0a37789d400b47bbdbc6c;p=deliverable%2Fbinutils-gdb.git

Move UNDEFWEAK_NO_DYNAMIC_RELOC to elf-bfd.h

Move UNDEFWEAK_NO_DYNAMIC_RELOC to elf-bfd.h so that it can be used by
other ELF linker backends.

	* elf32-ppc.c (UNDEFWEAK_NO_DYNAMIC_RELOC): Moved to ...
	* elf-bfd.h (UNDEFWEAK_NO_DYNAMIC_RELOC): Here.
	* elf64-ppc.c (UNDEFWEAK_NO_DYNAMIC_RELOC): Removed.
