Just to be clear, that CONFIG_SHELL workaround was a giant pain to figure out.
The errors produced when /bin/sh = dash are not at all obvious as to the root
cause, and finding the existence of CONFIG_SHELL takes a certain familiarity
with autoconf, which I didn't have until significant manual reading.

Seems pretty draconian to leave that for foreign distro devs if we do indeed
have a good fix.
