My only question is if we want an OS version check as the FreeBSD driver does now for libc++ vs libstdc++? FreeBSD started using libcompiler_rt for libgcc.a in 9.0.

What's wrong with the symlink approach?

I think it is overkill to look for fbsd 8, it was eol-ed 2015, and 9 in 2016.
A native build of clang 7 on fbsd 8 would be difficult to pull off, needing at least 1-3 intermediate clang's/gcc's

The symlinks were useful in the transition from gcc to clang.
Now they don't serve any purpose.
Clang uses libcompiler_rt, not libgcc.
