    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.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).
