It looks like --with-zephyr may be all you need to do that. It looks like
that will make us test for /usr/athena/include/zephyr then
/usr/include/zephyr then /usr/local/include/zephyr existing and attempt to
use the first of those that we find.

But for that usage (and the matching one for GG) I think I'd rather make
it explicit and rename --with-zephyr to --with-external-zephyr (or turn it
around and make it --with-internal-zephyr and leave external usage as
default). Not that this matters much and may not be worth the disturbance
it causes.

But, my proposed change, extended to include zephyr would mean that to
specify a non-standard location would involve using
'ZEPHYR_CFLAGS=-I/usr/include ./configure ...' instead of './configure
--with-zephy=/usr' (though I also just noticed that we interpret
--with-zephyr=$zpath to set both $zpath/include and $zpath/lib but
--with-zephyr only sets the location of the include directory which is
interesting).
