The session extension has a --with-mm flag that tells it to build
the mm backend ("mm" is the name of the library). However, that
backend is not thread-safe, and mod_mm.c will refuse to compile if
the --enable-maintainer-zts flag was also passed to the configure
script.
Rather than crash halfway through the build, this commit adds a check
to the session extension's config.m4 file. If both --with-mm and
--enable-maintainer-zts are "on," then the configure script will
die and explain that they can't be used together.
