Re: gas/ELF: don't accumulate .type settings

git commit f2d4ba38f5 caused many failures for mips-sgi-irix targets,
and added a new test that failed for aarch64, nds32, and rl78.
The mips failures are due to BSF_OBJECT being set in many cases for
symbols by the mips .global/.globl directive.  This patch removes that
code and instead sets BSF_OBJECT in a target frob_symbol function,
also moving the mips hacks in elf_frob_symbol to the new function.

Note that common symbols are handled fine in elf.c:swap_out_syms
without needing to set BSF_OBJECT, so that old code can disappear.

	* config/obj-elf.c (elf_frob_symbol): Remove mips hacks.
	* config/tc-mips.h (tc_frob_symbol): Define.
	(mips_frob_symbol): Declare.
	* config/tc-mips.c (s_mips_globl): Don't set BSF_OBJECT for irix.
	(mips_frob_symbol): Fudge symbols for irix here.
	* testsuite/gas/elf/type-2.e: Allow random target symbols.
