Workaround a bug in tinderbox/pointyhat that leaks /sbin/mount_fuse
from the host when host is HEAD.
This leads when building packages for 9.x or 8.x to ignore the fuse-kmod
dependency the fuse ports should have on those versions.
- Add a short usage description inside each Uses/*.mk
- Simplify logic for Uses/bison.mk and make error message more informative
- Add error handler for Uses/fuse.mk and Uses/pathfix.mk
