[PATCH v2] make: add install-stripped target

[PATCH v2] make: add install-stripped target

[Bagas Sanjaya]

Add the target that install Git with stripped executables.

install and install-stripped share the almost-same recipe, with the
difference only on passing arguments to $(INSTALL). In order for this to
work properly, installing all programs ($(ALL_PROGRAMS) and
$(install_bindir_programs)) must be splitted into compiled programs and
scripts install portion. For compiled programs, pass $(INSTALL_OPTS),
since stripping is only meaningful for them and not scripts.

 Changes from v1:
 - Share recipes between install-stripped and install targets (suggested
   by Junio)
 - Don't delete 'strip' target. There may exist scripts that depend on
   that target. Once this patch is integrated, deprecation notice can
   be displayed when running the target, but it is done in separate
   patch.
