(actually, i think it's the TOOLCOMBO variable you're thinking of.)

this is something i've wondered about for a while.  if you really
wanted to be pedantic, the TOOLCOMBO variable would technically
include *all* of the versions of gcc, glibc, binutils, the linux
kernel, whether sanitized headers were used, and maybe even the
version of the host compiler.

obviously, that's absurd but it sure seems to be tending in that
direction.  what about just overriding that whole combo with some
meaningful (to the builder) keyword.  for instance, if i'm building an
ARM toolchain for my zaurus, i'd just as soon replace that whole
string with "zaurus" since i would know what that meant, and i really
don't care if anyone else understands the underlying combination.

thoughts?
