lld for LLVM 10 always had --no-threads as I now understand
and stable/12 still has/uses/needs LLVM 10.0.1 (with
updates).

That means that lld from LLVM 11 was in use (FreeBSD
13's system ld). The build was probably trying to build
some LLVM 10.0.1 final+ materials for bootstrap style
build use in later build stages (older FreeBSD targeting).
It likely had not gotten to the stage of building freebsd
stable/12 material itself.

Attempting to build devel/llvm10 might well have the same
issue without having to involve an extra FreeBSD source
tree or build.
