People who do crosscompilation are _required_ to have a clue about the
difference of development libraries and system libraries.  No need
pampering for them, even though something more explicit like the
previous Yes/No list might be worthwhile.

The people we have to be concerned with are native compilers, those
that start with a tarball in order to arrive at a working Emacs on
their current system.
