 Well, three changes:

1. use the old disfile, Fabrice still hasn't committed anything new
(the copy on dad-answers.com is only there for one day each)
2. CFLAGS+= -I${LOCALBASE}/include doesn't get propagated to the build
at least here, need to patch Makefile.target instead
3. need ${WRKSRC}/kqemu/Makefile.freebsd instead of ${WRKSRC}/kqemu/Makefile
