    testsuite: Skip gcc.dg/ipa/pr77653.c for CRIS
    
    CRIS defines DATA_ALIGNMENT such that alignment can be
    applied differently to different data of the same type, when
    "references to it must bind to the current definition"
    (varasm.cc:align_variable).  Here, it means that more
    alignment is then applied to g, but not f, so the test-case
    fails because another message is emitted than the expected:
    a same-alignment test dominates the not-discardable test,
    and we get "Not unifying; original and alias have
    incompatible alignments" rather than "Not unifying; alias
    cannot be created; target is discardable".  Because this
    DATA_ALIGNMENT behavior for CRIS depends on target options,
    and this test is already artificial by the use of -fcommon,
    better skip it.
    
            * gcc.dg/ipa/pr77653.c: Skip for cris-*-*.
