Log Message:
Change the ONLY_FOR_PLATFORM pattern, so that it no longer matches
against 9.0, 9.1, 9.2 or 9.x_STABLE, only 9.99.* and subsequent
releses.  The set of libraries this is compared against is what's
in 9.99.92, but the binaries are from 9.0, of course.

Bump PKGREVISION so that we pick up the changes from
compat_netbsd/INSTALL.ELF, to protect against removal of base system
symlinks, ref. PR#56597.
