[bfin] PATCH: Add a prefix underscore to _GLOBAL_OFFSET_TABLE_, _PROCEDURE_LINKAGE_TABLE_ and _DYNAMIC

["Jie Zhang" <jzhang918 at gmail dot com>]

I have installed this patch, which has been in ADI's CVS repository
<blackfin.uclinux.org> for a long time. It's needed for supporting
Blackfin FDPIC ELF debugging. The patch adds a prefix '_' to
_GLOBAL_OFFSET_TABLE_, _PROCEDURE_LINKAGE_TABLE_, and _DYNAMIC.

Jie
	* elf32-bfin.c (bfin_check_relocs): Use __GLOBAL_OFFSET_TABLE_
	instead of _GLOBAL_OFFSET_TABLE_.
	(bfin_relocate_section): Ditto.
	(_bfin_create_got_section): Ditto.
	(elf32_bfinfdpic_create_dynamic_sections): Use
	__PROCEDURE_LINKAGE_TABLE_ instead of _PROCEDURE_LINKAGE_TABLE_.
	(bfin_finish_dynamic_symbol): Use __DYNAMIC instead of _DYNAMIC.
