    testsuite: normalise away `ld`-warning on AIX
    
    On AIX, `ld` doesn't support `-x` and ignores it. However, a warning is
    emitted to stderr which ends up triggering false positives in some of
    GHC's testsuite tests. So we simply filter out that noise as part of
    normalising stderr.
