pkgsStatic.stdenv.cc.cc: put static libs in $lib
libtool requires the library files its .la files describe to be in the
same directory as those files.  We only do this for compilers without
shared libraries, so that the libraries in $lib are always the
libraries the package set is supposed to use.

The GNU Compiler Collection includes compiler front ends for C, C++,
Objective-C, Fortran, OpenMP for C/C++/Fortran, and Ada, as well as
libraries for these languages (libstdc++, libgomp,...).
GCC development is a part of the GNU Project, aiming to improve the
compiler used in the GNU system including the GNU/Linux variant.
