[PATCH 3/4] Makefile: factor common configuration in git-default-config.mak

[Matthieu Moy <Matthieu.Moy@imag.fr>]

Similarly to the extraction of perl-related code in perl.mak, we extract
general default configuration from the Makefile to make it available from
directories other than the toplevel.

This is required to make perl.mak usable because it requires $(pathsep)
to be set.
