gcc-7.3: Fix build on ppc64le hosts
When building on ppc64le hosts that have GCC 8 (such as Ubuntu 18.10)
the GCC build bootstrap fails.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86162
This is a fix that was applied to the upstream GCC 7 branch.

+ * lex.c (search_line_fast): Remove illegal coercion of an
+ unaligned pointer value to vector pointer type and replace with
+ use of __builtin_vec_vsx_ld () built-in function, which operates
+ on unaligned pointer values.
