HEAD: cross-compile test new testsuite

[Ralf Wildenhues]

This gets the new test suite from several failures to no failures (but
of course a number of skips) for a gnu-linux -> mingw cross-compile.
(The old test suite also show a couple of recent regressions, sigh;
more about that in another mail.)

OK to apply to HEAD?

Cheers,
Ralf

        * tests/testsuite.at (PREPARE_TESTS): Extract host_alias.
        Set configure_options appropriately.
        (LT_AT_CONFIGURE): New macro.
        (LT_AT_BOOTSTRAP): Use it.
        * tests/early-libtool.at, tests/standalone.at: Likewise.
