Use --target for target architecture specification
Instead of using a combination of ARCH and --host, use --target.
It's possible to have host != target. For example, building a ppc
kexec binary for a ppc64 kernel. In this case, the kexec binary is
compiled for 32-bit, while the purgatory object is 64-bit.
