Oops.  I was politely reminded off list that my config was *not*
attached.  It should be now.  :>

During the course of continuing experimentation today I've run into a
few more headaches, all of them related to configure scripts (which I
should have expected after googling, rtfm'ing, yada yada).  For example,
configure is bound to look around for libs or headers and find stuff
that is glibc-based (in /usr/{lib,include}, /usr/local/{lib,include},
etc) rather than the uClibc-based stuff, thus causing all sorts of
havoc.  Two ways around this:
	1) Use a chroot(). :)  As recommened on the uclibc site.
	2) Hack/patch offending sources.
Both ways are time consuming and problematic.  And even if you use a
chroot() some source hacking is close to inevitable.
