You're going to have to be more precise in your description for me to
tell. I am not sure from this description whether this describes a
failure to build or an unusual kind of output while otherwise building
successfully or maybe even something else.

It's because of all the btfixup stuff in the sparc32
build machinery, William.
He doesn't need to give any more description, it is clear
what the issue is.

It's known behaviour for 2.4.x (2.6.x should work). Keith had a patch,
although I believe it wasn't applied because of suspected side effects.

Yes, and there's a patch for it I got long ago, I think from Pete who
in turn got it from someone else (feel free to speak up). I doubt
this was ever integrated, since 2.4 is dead and buried.

Hmm. Now that I've seen the patch I know what people are on about,
but maybe I'm too dense today to figure out what "silently finishes
before linking" means, as I've yet to decipher it even afterward.

Mea culpa - it means that I forgot to save a logfile.
make vmlinux -j6 completes all of the compilation steps but ends
without complaint before starting the final linkages.

Yes, 2.6.x works; the problem for me on 2.4 is that a make -j2 will omit
building of init/, and the compile will fail because init/main.o is not
found.
Even though 'vmlinux' explicitly has a make dependency on init/main.o.
