testsuite: Fix gcc.dg/attr-weakref-1.c on Solaris/x86 with as [PR70582]

gcc.dg/attr-weakref-1.c FAILs on 32 and 64-bit Solaris/x86 with the
native assembler:

FAIL: gcc.dg/attr-weakref-1.c (test for excess errors)
UNRESOLVED: gcc.dg/attr-weakref-1.c compilation failed to produce executable

Excess errors:
Assembler: attr-weakref-1.c
        "/var/tmp//ccUSaysF.s", line 171 : Multiply defined symbol: "Wv3a"

This is a bug in the native as, which isn't seeing fixes recently.

Since only a single subtest is affected, this patch omits that one.

Tested on i386-pc-solaris2.11 (as and gas) and x86_64-pc-linux-gnu.

	gcc/testsuite:
	PR ipa/70582
	* gcc.dg/attr-weakref-1.c (dg-additional-options): Define
	SOLARIS_X86_AS as appropriate.
	(lv3, Wv3a, pv3a): Wrap in !SOLARIS_X86_AS.
	(main): Likewise for chk (pv3a).
