Help with some makefile hackery

Good point! Not something I had considered (but should have). Is there
a way to propogate that status through the pipe? I am using 'tee' so
that the master build (which invokes the top-level make) can also see
the make output. But going back and reading the man page on 'sh' shows
me that on a pipline, the status is the status of the *last* command.
Maybe I should do this instead?
cd src; ./amd64-kernel.sh 2>&1 > build_amd64_kernel.log; \
tail -f build_amd64_kernel.log
It is not too clear if the status is the last one in a compound command.
I will give that a try.
