Thanks for the solaris fix.  (I think I've seen that before,
but didn't carry it forward to binutils-2.15.  I will now.)

The following change is a bit much, though:

This means the resulting toolchain will only be able to
generate executables that match more or less exactly the
kernel sources it was built with.  Are you sure you want that?
Some users will expect their programs to be able to run on
older kernels (like 2.4.3).
