gcc: Fix building on ppc64le GCC 8 host
When building on a ppc64le host we see this error: build/genmatch --gimple ../../gcc/match.pd \ > tmp-gimple-match.c ../../gcc/match.pd:120:1 error: expected (, got NAME negative value by 0 gives -0, not +0. */ This was reported upstream[1] and fixed on the GCC 6 [2] and GCC 7 [3] branches: Backport from mainline 2018-01-10 Kelvin Nilsen <kelvin@gcc.gnu.org> * 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. The patches included in Buildroot contain just the code changes, and not the changelog, to make it easer to manage backporting. Tested on Ubuntu Cosmic ppc64le.
