GNU C Library builds on my GNU/Linux, corrections still necessary

The problem with the previous commits was that MPFR (and thus its
dependecy: GMP) conflict with the GNU C Library's internal implementation
of GMP functionality. So the AWK for building GNU C Library is not built
with MPFR and the problem has been fixed.

However, there are still two problems with the current build:
 1. Many programs (like `gzip' and `tar' that were checked), need patchelf
    to actually link with our internal C library.
 2. There was a compilation error while building `ncurses' with C++ because
    of the new C library.
