[committed] Fix MIPS16 global calls failures

[Richard Sandiford]

For this one I think we should use a linker script to get consistent
addresses, like we do for several other tests.

Also added alignment directives to make the alignment consistent.

Tested on various MIPS targets and applied.

ld/testsuite/
	* ld-mips-elf/mips-elf.exp (mips16_call_global_test): Use the
	no-shared-1.ld linker script.
	* ld-mips-elf/mips16-call-global-1.s: Add alignment directive.
	* ld-mips-elf/mips16-call-global-2.s: Likewise.
	* ld-mips-elf/mips16-call-global-3.s: Likewise.
	* ld-mips-elf/mips16-call-global.d: Use 50000 as the base address.
