We set some variables for linking zlib to '' which we shouldn't do. Let
the Makefile sort these things out.

libgccjit is still under development and, despite its name, may also be used for
ahead-of-time compilation.
Documentation can be found on the gcc website:
https://gcc.gnu.org/onlinedocs/jit/internals/index.htmlhttps://gcc.gnu.org/wiki/JIT
With this change it's possible to enable the building of the libgccjit. It's
enabled as a language (with --enable-languages=jit) even if not a language
frontend at all.
The main changes are related to the requirement of having everything host side
built as Position Independent Code (PIC) with --enable-host-shared. GCC has the
needed logic for building its dependencies (mpc, gmp, mpfr, ...) correctly when
built "in-tree", which is not the case with crosstool-ng (see
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=05048fc29f0)

zlib refuses to run configure with mingw32 host and insists that
win32/Makefile.gcc is used instead.
This requires a change in this Makefile to support static-only builds.
Fixes#694.

The latter does not prevent zlib's configure from overriding 'AR' with
/usr/bin/libtool on macos, and that breaks canadian crosses.
