This is an old one but I am trying to clean up the failing tests on powerpc 64
that have just been ignored.

This isn't really a regression as it looks like it has never worked right on
power 7.  It works OK on other power hardware including other BE.  I am pretty
sure it is just something not supported on power 7.

make -k check-gcc RUNTESTFLAGS=vect.exp=gfortran.dg/vect/pr83232.f90
