libtool head stresstest.at uses $host, not $host_os

[Peter Ekberg]

Hi!

In stresstest.at, there's a check if the host is windows,
and the tests w/o -no-undefined are skipped if it is.
However, the test is wrong, so here's a patch.

Unfortunately, $host_os is not set, so I had to insert
another wildcard in the cases instead...

        * tests/stresstest.at [Cygwin, MinGW, PW32]: Really
        disable the tests w/o -no-undefined.

Cheers,
Peter
