glibc 2.14 later should have correct fma{,f,l} implementation, except for
targets which don't support exceptions properly and thus round-to-odd trick
doesn't work there, and except for PowerPC long double (where it is even
unclear what actually should fmal do because of the floating point format weird
properties).
