Likewise, binutils has no idea about any of these new targets either, so we 
fix that up too.. now we're able to actually build a real toolchain for 
sh2a_nofpu- and other more ineptly named toolchains (and yes, there are more 
inept targets than that one, really. Go look, I promise).

textrels are bad for forcing copy-on-write (this affects everyone),
and for security/runtime code generation, this affects security ppl.
But in either case, it doesn't matter who needs textrels, it's
the very fact that they're needed at all.

	* ld/ldmain.c (main): Change textrel warning default to true.
