Patch to build lang/gcc6 on ppc64 with clang if available

Through testing I was able to build lang/gcc6 and lang/gcc7 with itself
(CC=gcc6 or CC=gcc7) and did not run into the tree-vect-loop.c issue, so I
placed the "-mno-altivec" flag under the ppc64 LLVM/Clang build only section
where it belongs to work around that build issue.
