Title:
  Emulation of a math function fails for m68k Linux user mode

Status in QEMU:
  Fix Released

Bug description:
  Please check the attached math-example.c file.
  When running the m68k executable under QEMU, it results in an 
  "Illegal instruction" error.
  Other targets don't produce this error.

  Steps to reproduce the bug:

  1. Download the math-example.c attached file.
  2. Compile it by running:
     m68k-linux-gnu-gcc -O2 -static math-example.c -o math-example-m68k -lm
  3. Run the executable with QEMU:
     /build/qemu-5.0.0/build-gcc/m68k-linux-user/qemu-m68k math-example-m68k

  The output of execution is:
     Profiling function expm1f():
     qemu: uncaught target signal 4 (Illegal instruction) - core dumped
     Illegal instruction (core dumped)

  Output when running on other targets:
     Profiling function expm1f():
       Elapsed time: 47 ms
       Control result: 71804.953125
