For additional reference:

No mention of any -lib32 , despite the reference to
FreeBSD-clang . But:
# pkg info -d FreeBSD-clang
FreeBSD-clang-16.snap20251014184832:
FreeBSD-lld-16.snap20250930012546
FreeBSD-libcompiler_rt-dev-16.snap20250923153156
FreeBSD-clibs-16.snap20251014203606 (libc++.so.1)

FreeBSD-runtime-16.snap20251014184832 (libz.so.6)
Does reference -lib32 :
# pkg info -d FreeBSD-clang | grep lib32
FreeBSD-clibs-lib32-16.snap20251014184832 (libc.so.7:32)
FreeBSD-clibs-lib32-16.snap20251014184832 (libgcc_s.so.1:32)
Also:
# pkg info -r FreeBSD-set-devel
FreeBSD-set-devel-16.snap20251008042735:
FreeBSD-set-base-jail-16.snap20251008042735
FreeBSD-set-base-16.snap20251008042735
So, both FreeBSD-set-base* eventually lead to FreeBSD-clibs-lib32 .
