I think this is an important question, because there seems to
be a misconception about native builds in mingw-cross-env:

A native build in mingw-cross-env should _never_ require a library
of the build system! In other words: The ubuntu packages zlib1g-dev
and libssl-dev are _not_ official requirements, so glib and gsoap
should also build on systems without zlib1g-dev and libssl-dev.

However, glib seems to work fine on systems without zlib-devel
libraries, and gsoap seems to work fine on systems without ssl-devel
libraries. So it seems that e.g. the native glib is compiled with
zlib just because zlib was _detected_, not because zlib is _needed_.

We should clarify this situation by adding corresponding "--disable-XXX"
options to the native builds. It would be great if you could try to
do that and if you could propose a corresponding patch.
