   Okay, I've got the right tools installed now, and I'm ready to commit
   this, if approved.

This patch does no harm, so it is OK with me, but I don't understand
why it is necessary.  If this patch is necessary, there are a number
of other places where a cache variable is tested without using quotes.
The autoconf macros should always arrange for a cache variable to have
a non-empty value; why is that not happening for you?
