fix apache "portable" runtime for x-compile

apr uses a braindead propietary pkg-config clone, which of course was
designed without a clue about crosscompiling or non-default install locations.
so trying to x-compile anything using apr is a PITA and requires a shitload
of hacks to fix.

they even ship their own libtool clone, which is of course buggy as well:
while it works for compiling, the link invocation calls a hardcoded "gcc"
rather than the linker name that was passed on the command line (would equal
to $CC).

as such, i had to use libtool.cross.gen to overwrite their libtool version,
however their usage case seems to hit a bashism in libtool.cross,
so we have to add bash as a dependency until libtool.cross gets fixed.
freetype: get rid of proprietary pkg-config clone

instead of settling on a single tool, which could be patched into
conformance, every shit lib on this planet now seems to think it's
a good idea to design their own crappy pkg-config replacement just
for their own lib.
of course all of these shit-config scripts break horribly in
x-compile scenarios, so let's just get rid of em.
fix serf for cross-compilation

not only is serf using the horrible APR framework which ships with
its proprietary pkg-config and libtool replacements (which of course
don't work properly), additionally it raises the horror by using the
scons buildsystem, which does everything gratuitously different and
is broken for cross-compilation as well.
fix svn for x-compilation

tons of hacks needed to work around the retardedness of APR and related
tools/libs, as well as the retardedness of the SVN configure script developers.
fix sdl-ttf for x-compile

special props go to the inventors of the braindead proprietary freetype-config
script, which is not compatible with cross-compilation and must be manually
tricked into compliance.
fix sdl-mixer for x-compile

special props to the authors of the braindead, propietary libmikmod-config
script, which is not compatible with cross-compilation and needs to be
manually tricked into compliance.
libmikmod: fix for x-compile
libmikmod: get rid of proprietary pkg-config clone

the mikmod authors belong to the bright lot of pkg-config clone sheeple
who want to break cross-compilation for every package.
fix couple pkgs for x-compile

build-stage: remove cruft
get rid of stage u experiment leftovers

STAGE U never was more than a prototype, and the same functionality
can now be achieved with a proper x-compile setup.
