[libiberty] does anyone use regex.c with REGEX_MALLOC?

libiberty cannot be replaced completely, because there are bits that
do not even exist in gnulib. And given the time frame, I don't think
Ayush will have time to replace all functions that already exist in
gnulib. This will need to be an incremental process. What I expect to
achieve is that we never need to re-implement in libiberty any
function that already exists in gnulib.

It is mostly build system bits. We need a build-system reviewer (or a
global reviewer). So far, Ayush haven't found any case that needs
upstream (gnulib) or gcc-specific changes.
