I'm just splitting out my original changes as suggested. The only thing
that hasn't worked so far was that I need to set $base_os, but the
configure script always sets this variable itself, regardless of if I've
already set it in the add-on configure fragment. The attached patch
fixes this so that configure checks that $libc_config_ok is not set
before it sets $base_os itself.

        * configure.in: Check $libc_config_ok before setting $base_os
        * configure: Regenerate.
