Subject: build template: native build: set ARCH according to OS and HOST_BITS.


The ARCH variable holds the name of a sub-folder where alternate,
arch-specific source files may be provided. This project currently
does not use such files (and none are anticipated), however other
midipix projects which share the same build template do.
