This indead would have been the best way to handle this, but moving
FreeBSD to this scheme would create a binary incompatibility.  Ie, once I
move FreeBSD 4.1 to a new Bintutils, binaries created under FreeBSD 4.1
would not be executable on FreeBSD 4.0.  That is not allowed in our
scheme of binary compatibility.  For FreeBSD 5.0-CURRENT, I can probably
get away with the above method.
