HWLOC (1.3.2rc1) tries:
            AC_LINK_IFELSE([AC_LANG_PROGRAM([[
                __attribute__((visibility("default"))) int foo;
                ]],[[int i;]])],
                [],
                [hwloc_add=])

While OMPI (1.4.5rc5) tries:
            AC_TRY_LINK([
                    #include <stdio.h>
                    __attribute__((visibility("default"))) int foo;
                    void bar(void) { fprintf(stderr, "bar\n"); };
                    ],[],
                    [if test -s conftest.err ; then
                        $GREP -iq "visibility" conftest.err
                        if test "$?" = "0" ; then
                            ompi_cv_cc_fvisibility="no"
                        else
                            ompi_cv_cc_fvisibility="yes"
                        fi
                     else
                        ompi_cv_cc_fvisibility="yes"
                     fi],
                    [ompi_cv_cc_fvisibility="no"])
                ])
