>Description:

when trying to use netbsd-3 in a chroot on -current post-newlock2, i
discovered that after upgrading libc and libpthread of the host system in the
chroot it is not enough to make some applications run (even though it was
stated to be).

the reason is that programs using some HMAC functions from libc couldn't find
the symbols, since they were moved from libc to libcrypt.  fair enough, i
thought that i'll just need to copy the new libcrypt over to the chroot.
while doing so i found out that libcrypt minor wasn't bumped even though its
ABI has changed.

>How-To-Repeat:
try running netbsd-3 chroot on -current.  copy the new libc and libpthread,
see some applications crashing.

>Fix:
bump libcrypt minor to mark ABI change.
