Is it not possible to pass this through #:make-flags? If not this LGTM,
but would be nice with a comment about why make-flags won't work.

The bundled "waf" script is bsd-3. Perhaps that can be removed, since it
uses waf-build-system? Otherwise this LGTM.

The waf-build-system doesn’t have any support for make-flags.  It flat
out ignores them and only runs “waf build”.  Whenever we want to change
flags in projects using waf we usually need to patch up the wscript(s).

I don’t know if there’s a standard way to amend certain flags.  If there
is we should add it to the waf-build-system.

The waf-build-system doesn’t actually pull in a copy of “waf”.  It
always just uses whatever “waf” comes with the sources.

I think the same applies for “waf” as to “configure” scripts.  We
usually don’t list the license of the generated “configure” script in
the license field.
