It does not work, for precisely the reason you mentioned.

It also appears pointless, as the only difference between te-generic.h 
and te-freebsd.h is the define of TE_FreeBSD in the latter, but that is 
not used anywhere in the RISC-V port.  So maybe that is why it "works", 
because it is unnecessary.  But that also means it is harmless and won't 
break anything if it goes in, with the order fixed of course.

I also don't see a copyright assignment for Ruslan.  This is probably OK 
as a trivial patches, but if there are more patches coming we would need 
a copyright assignment.
