Changing the HAS_FPU setting in uClibc's config is insufficient
by itself. All that really does is tell uClibc not to try to
save/restore floating point registers when doing things like
setjmp/longjmp.

Amazingly enough, I'm testing an arm soft-float buildroot build right
now. I should have my latest fixes in buildroot by tomorrow.
