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.
