I don't really have any experience with FreeBSD internals at all, 
so I can't really judge the situation, but if the BSD libc 
allocates TLS variables for new threads the same as the GNU libc 
does (i.e. at the start of the new stack), then it is potentially 
very little difference (as the ELF section iteration mechanism 
also seems to be supported).

I don't think this will be an extremely hard issue to solve, but 
it depends on somebody actually spending some time on this (and 
for myself, a 2.063-based release, Linux shared libraries, and 
the Win32 wrong code bugs seem more important, given that FreeBSD 
is a pretty niche OS…)
