NetBSD 11 beta users: please update base and rebuild pkgs

[Martin Husemann <martin%duskware.de@localhost>]

Hey folks,

if you are building pkgsrc pkgs on NetBSD 11.0_BETA, please note that we
have pulled up fixes to the libcrypto build system in base. This means
that not everything using libcrypto from base needs to also link against
libpthread. But the fix came with small fallout: libpthread went from
version 1.5 to 1.6.

If you plan to use your pkgs later and for other 11.x machines it would
be a good idea to update your 11.0_BETA installation to the latest
avilable build now.

If you are running bulk builds for 11.0, it would be best to also rebuild
everything using libpthread or libcrypto.

Sorry for any inconvenience this might cause. We normally do not allow such
pullups on stable branches, but since 11.0 is (unfortunately) still in
beta stage this got an exception.

Luckily with this resolved we can proceed with the release cycle now.

Martin
