Sure, but that was my question: how?  That 'make static' target can drop -lbfd,
-lSDL etc. from the link line but all of the '.o's that we've already built
either may depend on one of those libs or may do something different because
CONFIG_HAS_SDL (or similar) was set.  The only way I can think of doing this is
to have 'make static' depend on a second set of
$(all_objects_except_without_optional_libs) which are built without
CONFIG_HAS_SDL etc., but that'd make Makefile fugly IMHO.

Unless, that is, CFLAGS (and thus CONFIG_HAS_SDL, has_SDL probing, etc.) can
somehow change depending on the make target.
