I know *I* would. ;-)

For that specific example, IMHO it's certainly fine to require
COMPILE_IN for targets where --sysroot should work out of the
box -- or of course that the user has moved the scripts to the
right place.  It's not a requirement of --sysroot to make sure
stuff is in the place pointed at.

Um, the same as one configure --with-sysroot? :-)

Having said that, I'm fine with documenting the restriction and
getting a solution that doesn't require --with-sysroot later.

I'm also ok with making this a cross-toolchain-only option
(independently).

FWIW.
