Fix all Mac OS X 10.1 Test Failures

[Noah Misch]

This patch against CVS HEAD, in combination with the Autoconf patch I just
submitted to address@hidden and cc:-ed to address@hidden, fixes all
outstanding test failures on Mac OS X 10.1 with the (default) zsh in /bin/sh.

The spirit and nature of this patch is the same as that of the Autoconf patch,
so please consult that posting for detailed rationale.  This patch does what the
aforementioned patch does to configure scripts to (a) the libtool script and (b)
the test scripts themselves.

Note that the code blocks this patch inserts come straight from earlier work by
Peter O'Gorman in libtool.m4.  I just found that it was needed in more places.

If libtool starts failing for you on Mac OS X 10.0 or 10.1 in the future, you
are welcome to bug me, by the way.  I welcome feedback on this patch as well.

        * ltmain.in: Unset the zsh GLOB_SUBST option, which makes zsh
        handle backslash quoting poorly, before doing anything else.
        * tests/defs: Likewise.
