elf.h: add EF_RISCV_FLOAT_ABI.

Browse source 
See code comments for details. I think everything we could reasonably
upstream from this file is now an upstream pull request. If they get in,
I'll try my luck with the arm32 TLS constant (which is a bit more
interesting because there's a probably obsolete conflict upstream, but
someone who knows about FreeBSD/arm32 would want to look at that).
