make buildkernel fails

[Christopher Illies]

A recently csup'ed CURRENT kernel failed to build on my
iBook G4. I have never before rebuild world and kernel on
a powerpc, so I don't know whether this due to some silly
mistake I made or caused by recent, or not so recent changes
to the source code. I csup'ed a few hours later and the
problem remained. make buildworld worked without problems.
My CUSTOM kernel has only debugging support commented out,
but is ortherwise identical to GENERIC (see below).

If my reading of the mailing list is correct, no more
patches are needed to rebuild world and kernel on powerpc,
right?

The only change I did to the GENERIC kernel config file is
commenting out debugging support:
