[PATCH] Added make options NO_GUI and WITH_P4IMPORT.

[Eygene Ryabinkin <rea-git@codelabs.ru>]

NO_GUI disables the building and installation of the git GUI part.
WITH_P4IMPORT enables the installation of the Perforce import script.

This patch was originally developed for the FreeBSD port of git,
but I think that it will not harm to integrate this patch into the
development tree.
