    ld: testsuite: Fix several CTF tests on 32-bit SPARC
    
    Several ld CTF tests FAIL on 32-bit SPARC, e.g.
    
    FAIL: Arrays (conflicted)
    
    The failure mode is always the same:
    
    ./tmpdir/array-char-conflicting-1.s: Assembler messages:
    ./tmpdir/array-char-conflicting-1.s:89: Error: Architecture mismatch on "return %i7+8".
    ./tmpdir/array-char-conflicting-1.s:89: (Requires v9|v9a|v9b|v9c|v9d|v9e|v9v|v9m|m8; requested architecture is sparclite.)
    
    The problem is that gcc emits v8plus code by default, and thus invokes
    as with -xarch=v8plus (equivalent to -Av8plus), while the testcase lacks
    the latter.
    
    Fixed by setting ASFLAGS to match.
    
    Tested on sparc-sun-solaris2.11, sparc-unknown-linux-gnu,
    sparcv9-sun-solaris2.11, and sparc64-unknown-linux-gnu.
