You can review the changes to make sure they make sense, and then use
`make update-symbols' to update the .expsym file in your source tree.

(If your NETBSDSRCDIR is a read-only null mount of a read/write tree,
you can still use `make update-symbols' by setting NETBSDSRCDIR_RW to
the path to the read/write tree.)

This probably arises from having generated the .actsym file with an
older bsd.lib.mk, from when it failed to filter those symbols out.

Just delete the .actsym file in your objdir (you can nuke all files
matching *.actsym -- they're cheap to recreate) and try again.

If you're still getting _end/_fini/_init after deleting any existing
.actsym and updating bsd.lib.mk, let me know.
