* config/tc-mips.c (md_pseudo_table): Handle .globl and .global.

	(s_mips_globl): New static function; needed for Irix 5 support.
	* ecoff.c (ecoff_build_symbols): If BSF_FUNCTION is set for an
	external symbol with no type, set the type to st_Proc rather than
	st_Global.  Don't set the index of an external st_Proc or
	st_StaticProc symbol unless it is also a local symbol.
