Re: port-mac68k/13078 (Mac 68LC040 problem)

The submitter is indeed right adding a nop before an fpu instruction does fix
the fpu emulation on the lc040...

The number of failed tests for libm is the same as for an '030 with fpu 
emulation and better than a qemu emulation of a full '040.

The number of failed libm tests are ~15 (1 expected).

Here is the diff to add nops for fpu instructions patching gcc / libc and 
locore assembly stubs:

I sincerely believe that this should be the preferred option as it means no 
special binaries just for the lc040 and uniformity amongst all m68k variants.

Best regards,

Nat
