[PATCH] elf: Don't use .set for alpha target

[H.J. Lu]

Since the .set directive of ELF/alpha target is different, define NO_SET
to 1 to use "=" for ELF/alpha target.

	* testsuite/ld-elf/elf.exp (ASFLAGS): Add "--defsym NO_SET=1" for
	alpha target.
	* testsuite/ld-elf/pr19789.s: Use "=" if NO_SET is defined.
