(In reply to James Le Cuirot from comment #15)

glibc assumes the existence of FPU for m68k, and GCC defaults to 68881:

$ m68k-glibc-linux-gnu-gcc -mcpu=3D68030 -E -dD - < /dev/null  | grep 68881
#define __HAVE_68881__ 1

The math tests do all build because different than mc68020, GCC defines
__DEC_EVAL_METHOD__ to 2 for mc68030.

The soft-float is only support for coldfire (__mcoldfire__) cpus.
