If I'm following things correctly how would the libc makefile be able to dermine which config file is in use on the machine (read out out of the dmesgs?) What if the build machine is building world to then be exported to a slower machine for the installworld - something that I do very often and has obvious benefits. I definitely agree the hooks should exist, making it easilly tweekable is important, though. If it is made default an obvious warning should be printed out in make-world noting that the libc generated will not work on pre-Pentium/XXX machines.
