Adds the necessary changes to docker, build,sh, and configs to allow FOS
to be built and operate on ARMv8.
NOTE: I have only tested this on arm64. I don't have any arm32 machines to test this on,
and so I make no promises
image. (Needs repo updated too, mastacontrola/fos-builder is available
with this modified docker image now.)
Update build.sh script to build 32 bit inits with the ARCH=i486 flag.
Otherwise it's building against 64 bit code which would, more or less,
make 32 bit init's unusable. Will monitor to ensure all builds
appropriately however.
