Bug 1451104 - part 1 - ensure compatible binutils for GCC; r=glandium GCC will pick up whatever `as` is first in PATH when trying to assemble files. It expects this `as` to have at least as many features as the `as` detected at configure time when GCC was originally built. We should ensure that GCC is always picking up an appropriate `as` by adding its base directory to the search path; otherwise, we get peculiar assembler errors.
