Log Message:
bsd.lib.mk: Let update-symbols know about ro vs rw source trees.
The update-symbols target is a tool for developers to update the
foo.expsym files from the actual list of exported symbols.
But if you have
/home/dev/netbsd/src
as a read-only null-mount of your real read/write source tree
/home/dev/netbsd/src.hg
as I do (in order to detect accidental writes to the srcdir which
should have gone to the objdir), `make update-symbols' doesnt work
because it tries to write to the read-only null mount.
With this change,
make update-symbols NETBSDSRCDIR_RW=/home/dev/netbsd/src.hg
will write instead to the read/write source tree.
