Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the

non-i386, non-unix, and generatable files have been trimmed, but can easily
be added in later if needed.

gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's
handy to have both available for reference for such little cost.

The freebsd-specific changes will then be committed, and once the dust has
settled, the bmakefiles will be committed to use this code.
