cc/gcc: add option to use system zlib

In some cases, it might be desirable to use the system zlib

Eg. because latest gcc seem to be totally borked when it comes
to multilib, and tries to build a multilib host zlib, when it
is *absolutely* *not* needed: we want mulitlib on the target,
not on the host! Sigh... :-(

     3   I'm still working on the solaris port an I have the same issue here.

     4   While trying to build the i686-nptl-linux-gnu toolchain under

     5   OpenSolaris, the problems appears during the make install rule of the

     6   libc function.

     7 

     8   The problem is that solaris tries to execute ld-linux.so.2, which is an

     9   elf 32 bits dyn lib, and it fails with a memory fault, not a "cannot

    10   execute binary file". Hence the build stops on this error.

    14   After digging a little, the problem comes from the

    15   glibc-2.6.1/posix/Makefile. It has been solved starting from glibc 2.7

    16   so I extracted a patch for glibc 2.6.1.
