I'm a little concerned that the & token isn't supported by all versions
of sed, either, but I couldn't find any examples... anyone have thoughts
on the portability of that?

Hmm. Why can't you do this with just one ``? There's no need for the
outer one and the outer echo at all as far as I can see, just pipe the
results of the case statement directly into the sed script, like this:
"CC=`case '$(CC)' in stage*) echo '$(CC)' | sed -e 's|stage|../stage|g';; \
*) echo '$(CC)';; \
esac | $(PREPEND_DOTDOT_TO_RELATIVE_PATHS)`"
?
