The -msoft-float option incorrectly removed MASK_68040_ONLY
in addition to MASK_68881.  This leads to incorrect
predefines and unwanted degradation of integer code.

There was just one place where we were using
TARGET_68040_ONLY to generate a floating-point
instruction without taking TARGET_68881 into account.

Tested on m68k-unknown-uclinux by comparing assembly
output of some selected testcases from gcc.c-torture.

OK for mainline? 3_4-branch?

OK for 3.4 branch if approved for mainline.
