Comment (by thomie):

 Did you test on x86, as it says in the description?

 The following two commits are relevant. The first one changes the test to
 only run for `WAY=optc` on x86. The second deletes `WAY=optc`. So now the
 test is always skipped on x86. That doesn't mean the problem is solved
 though!

     ffi005: run only the via-C way on x86 platforms
     due to 80-bit vs. 64-bit precision leading to floating point
     differences when using the native code generator.  -fvia-C uses the
     -ffloat-store gcc sledgehammer to avoid this.

     Remove any mention of optc/profc from all.T files
