Subject: [PATCH] Add an option to disable decimal

This patch replaces the existing --with-system-libmpdec option with a
--with-libmpdec={system,builtin,none} option, which allows to tell
Python whether we want to use the system libmpdec (already installed),
the libmpdec builtin the Python sources, or no libmpdec at all.
