Use soft-fp fma for no-FPU ColdFire (bug 13304).
Systems without floating-point exceptions and rounding modes should use the soft-fp versions of fmaf and fma, not the sysdeps/ieee754 versions that rely on setting rounding to zero and testing for the "inexact" exception; this has been noted on <https://sourceware.org/glibc/wiki/PortStatus> for some time. This patch makes no-FPU ColdFire use the soft-fp files; sfp-machine.h is made to include the nios2 version of sfp-machine.h which seems sufficiently generic for 32-bit systems. [BZ #13304] * sysdeps/m68k/coldfire/nofpu/s_fma.c: New file. * sysdeps/m68k/coldfire/nofpu/s_fmaf.c: Likewise. * sysdeps/m68k/coldfire/nofpu/sfp-machine.h: Likewise.
