[If work/gcc-7.2.0/gcc/tree-vect-loop.c avoids the
name vec_step then it avoids the conflicting use
for altivec support in the powerpc64 context. I
used vec_step_renamed as the name in
work/gcc-7.2.0/gcc/tree-vect-loop.c instead.
Similarly for devel/powerpc64-gcc and likely
other variants.]

It turns out that avoiding the non-global identifier
vec_step allows getting past this issue. For lang/gcc7 :
