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... :-(

     1 Patch to correctly handle the MIPS case.

     3 It was build up by Yann E. MORIN <yann.morin.1998@anciens.enib.fr> from some
     4 bits gathered from buildroot, which is LGPL v2.1

    17 I personnaly believe that the resulting code should therefore be
    18 LGPL v2.1, but don't believe me, ask your lawyers!
