I'm not using that bootstrap yet because it lacks some features I
really need:

1) the ability to specify additional flags to be used to build gcc.  I
currently have to append a strtoul-related flag to CFLAGS and
BOOT_CFLAGS so that I can build g77 on SunOS 4.1.3, and I can only do
that by using the bootstrap target in the gcc directory.

2) the ability to continue a build from a given stage on, as I can do
with bootstrap2 & bootstrap3.

Also, I don't think bootstrap should make compare.  Maybe I'm just
used to the ol' gcc bootstrap behavior, but I don't think building gcc
has anything to do with comparing it.  Maybe make check should do
it...

Here's a patch that provides bootstrap[23] targets, and removes the
BOOT_CFLAGS from the make invocation.  Doing this, BOOT_CFLAGS may be
overridden, and, if it is not, the default BOOT_CFLAGS from the gcc
Makefile will be used.
