  94 #      is unusual for x86, it seemed the best approach considering the
  95 #      limitations in the gcc floating point emulation library.
  96 #   For arm, soft float uses the usual libfloat routines.
  97 #   Custom specs files are used to set the default gcc mode to soft float
  98 #      as a convenience, since you shouldn't link hard and soft float
