This breaks the build when VFP isn't enabled at compile-time, because then
the libc_* functions aren't defined. You need to have the <fenv.h>
functions conditionally call libc_* functions that always use VFP (and are
always defined), while those VFP-using functions are only conditionally
used within the rest of libm. I.e., I think the __SOFTFP__ conditionals
in fenv_private.h should only control the definitions of libc_* to use
libc_*_vfp, not the definitions of the libc_*_vfp inlines.
