It's going to be a couple of interesting days for sure!

Fair enough. But does the build directory have to be per-target or
would you be OK with fixing the build directory to e.g. build/ right
next to src/ ?

What I like about the Linux build is that there's only ever one dir
that you "make" in, and when make is done it always produces
arch/*/boot/bzImage.

The current structure could be simple too, if the buildtarget step
could be skipped, and there was no need for via/epia-m/epia-m but
only via/epia-m, and that's where you go to make config && make to
get a linuxbios.rom.

Or maybe we'll extend it?
