FreeBSD/ports 41973f3 (r518121)lang/gcc8-devel/files patch-clang-vec_step

Forward port r509607 | gerald | 2019-08-22 from lang/gcc8 since this has
not been addressed upstream yet:

  clang on rs6000/powerpc* unfortunately poisons user namespace by default
  (without any special options or include files being required).

  Until that changes (or GCC changes) we need to avoid using vec_step as a
  variable name.
