* real.c: Avoid parse error if FLOAT_WORDS_BIG_ENDIAN is
not a compile-time constant for the non-IBM case.
* config/arm/arm-protos.h (arm_float_words_big_endian): New
prototype.
* config/arm/arm.c (arm_float_words_big_endian): New function.
* config/arm/arm.h (TARGET_CPU_CPP_BUILTINS): Define __VFP_FP__
if TARGET_VFP and not TARGET_HARD_FLOAT.
(ARM_FLAG_VFP, TARGET_VFP): Define.
(FLOAT_WORDS_BIG_ENDIAN): Use arm_float_words_big_endian.
[ Missed arm.h in previous checkin, and pasto'd ChangeLog entry, which
is now corrected. ]
