GCC not building on GNU/Linux system with incomplete complier
On some GNU/Linux distros, the compiler is separated into `multilib' mode
(for 32-bit and 64-bit support) and by default the extra component of the
compiler is not installed! In such systems for now, we are just creating
symbolic links to the host's compiler (similar to Mac).
While testing, I noticed that we weren't passing a "$downloader" option to
the downloading script of `dependencies.mk' and `dependencies-python.mk'.
Also, I noticed that the Cython and Python-pkg-config packages didn't have
setuptools as a dependency! Both have now been fixed. Also, Cython's
tarball name is now all small-caps (as in all the other tarballs).
