10.0_BETA w/MKNSD=yes build fails after OpenSSL update

["John D. Baker" <jdbaker%consolidated.net@localhost>]

The recent mega-pull-up of heimdal, bind, and OpenSSL 3.0 to
NetBSD-10.0_BETA:

  https://mail-index.netbsd.org/source-changes/2023/08/11/msg146890.html

breaks builds which set MKNSD=YES.

Example target sparc (i386 shows same failure):
