Enable support for building libgccjit
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.html
https://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)
