Subject: [PATCH] gambit: 4.8.6 -> 4.8.8-f3ffeb6

Using a yet unreleased development version of gambit,
so as to be able to build a recent gerbil.

Update the way gambit is bootstrapped, which involves building a
release version of gambit (which for a development gambit, is not the
same version as the current version of gambit).
