I hate to respond to my own post, but I think I just made some headway.
Out of frustration with Google, I started digging through my own
archive of gentoo-embedded. I found a reply from Mike F for a similar
problem. It doesn't appear to be in the archives, so I'll quote it here:
Re: [g-e] Cross compiling fails because of missing dependencies
on 20070324
you're expecting the cross-compiler to magically know
about all the headers/libraries in ROOT ... while this
would be nice, it'd be a breakdown in the logical
separation that exists with ROOT
if you did `ROOT=/usr/$CTARGET emerge lzo --nodeps`,
i bet it'd work then ...

This sounds like the solution to my problem, although I'm a bit hesitant
to muddy my ${SYSROOT}...
Also, this appears equivalent to 'xmerge --nodeps lzo', ie, dump it in
${SYSROOT}, so I'll give it a shot.
Is this what most people do (libs/headers to SYSROOT)?
Jason.
