building Ubuntu kernels on a Red Hat host

[Roger W Nichols]

Robie--

I have SHELL set as /bin/bash in both cases.

My best guess is there is something different about the default
configuration of make, but I do not know how to check that

This makes me wonder why you're seeing different behaviour.

On Debian and Ubuntu, /bin/sh runs dash. What does RHEL do? Could a
difference here explain the difference in behaviour that you're seeing?
The SHELL make variable might be useful here to experiment with.

I can't speak for the kernel team but I'd expect Makefile shell bits to
be POSIX compliant, and if it's not, then I'd file a bug with a patch.
Assuming that's the cause.
