Add an ARCH variable and replace the hardcoded "amd64" with a string derived from `uname -m` in order to build non-x86 initramfs images. Signed-off-by: David Hendricks <david.hendricks@gmail.com>
Replace crossgcc-i386 with crossgcc-${ARCH} based on the
architecture passed in from Makefile.inc.

Make VPD support optional in order to enable builds for more mainboard targets. VPD should still be added for production usage, this is mostly intended to help get new targets up and running. Signed-off-by: David Hendricks <david.hendricks@gmail.com>

GOARCH needs to reflect the target architecture. GOROOT needs to point at GOROOT that is compatible with the host. Signed-off-by: David Hendricks <david.hendricks@gmail.com>

This adds QEMU, Linux, and coreboot configs for ppc64le. For now we assume power8 as the coreboot qemu target, but this will likely change soon. Signed-off-by: David Hendricks <david.hendricks@gmail.com>

Changed the branch name to crossbuild. "non-x86" is not accurate since the goal is to build to/from various host types, including x86. |

This makes the build files more generic so that we can easily build non-x86 targets. Basically, it removes hardcoded assumptions about x86_64/amd64 and makes VPD optional since coreboot does not support it on all targets.
So far I've built successfully on ppc64le. Next up: RISC-V, Aarch32/64, etc...
TODO: Figure out how to invoke qemu/qemu-system for each target.
