Yes, we need to fix that somehow.  There was a point when
--enable-checking was only a factor or two or so; this made it
possible for people to build that way regularly.  Now, it is basically
impossible; only the truly dedicated can brave it.

We should break ENABLE_CHECKING into
ENABLE_RTL_CHECKING/ENABLE_TREE_CHECKING/etc so that we can get some
more manageable options.
