I think it depends more on what distributions ship than what
the release date was.  E.g., if you look around the last couple
stable releases of popular stable distros (e.g., ubuntu, debian, fedora),
which GNU Make version did they ship?  If the GNU Make version shipped
by default is not 4.x, is there an easy optional rpm/deb package
for GNU Make 4.x available?

This was the same kind of investigation that led to the GCC 4.8
minimum requirement.

Also, looking around the GCC compile farm machine (including the
/opt/ dirs) for what is available may be a good hint/proxy for
determining whether bumping the requirement could cause trouble
for people.
