So bootstrap should provide mksrc.  
The latest version of bmake adds support for FindHereOrAbove
so you can run boot-strap -m .../mk
I've fixed ShareDir so it won't return /share (unless it exists),
so if neither share_dir nor /usr/share contain a mk dir, we
can use FindHereOrAbove to look for one, but it would be better to be
told where.

/usr/share/mk shouldn't be used on anything but NetBSD, so using
.../mk might be best in this case too?
