[PATCH] ld: Skip unsupported static executable tests

Hi H.J.,

I just tested it on i386-pc-solaris2.11: one change in ld testresults is
unexpected:

-PASS: Common symbol override test 3a
-PASS: Common symbol override test 3b
+UNTESTED: Common symbol override test 3a
+UNTESTED: Common symbol override test 3b

Otherwise the FAILs from the PR are gone as expected.

Thanks.
        Rainer
