I'll take a look tomorrow. Seems FreeBSD is going to use it for both x86_64 and i386 targets for start? That means we also might want to revisit D32354 <https://reviews.llvm.org/D32354>.
It was reverted.

FTR and to answer the comment from freebsd.org page above, which was
"They did not stated why DF_STATIC_TLS was considered as 'not needed'.":
