Tweak binutils testsuite

Tweak binutils testsuite

Some targets provide aligned .bss sections, so explicitly align.
msp430 and rl78 emit "magic" symbols when assembling symbol.s, and
mips targets emit STT_OBJECT rather than STT_NOTYPE syms.

	* binutils-all/strip-12.s: Align .bss section.
	* binutils-all/strip-12.d: Adjust.
	* binutils-all/symbols-1.d: Allow extraneous symbols.
	* binutils-all/symbols-2.d: Likewise, and V for weakened syms.
	* binutils-all/symbols-3.d: Likewise.
	* binutils-all/symbols-4.d: Likewise.
