given that the test also FAILs on Linux/sparc64, it's not a
glibc-vs-non-glibc issue.

FWIW, there are both Solaris/SPARC and Linux/sparc64 systems available
in the cfarm; no need to build one yourself.  But fully agreed, running
a full bootstrap to verify a single testcase is a bit much if it can be
done more easily ;-)

I've just tried the patch on both sparc-sun-solaris2.11 and
i386-pc-solaris2.11 and the test now PASSes on both.

Thanks.
