Add minimal-system-image-x86_64
This element produces a disk image that boots in QEMU. It has a kernel,
BusyBox, and little else; but should be suitable as a basis for more
grand endeavours.
This disk image we produce is 53MB. I spent a while trying to get this
as small as possible and this is as far as I got:
* The boot partition seems to have a minimum size just over 32MB;
lower than that and SYSLINUX fails to write the boot sector. The
combined size of the initramfs and kernel is about 32MB, so I
imagine that's what limits us.
* The main partition is limited in size only by the amount of binaries
that we put there.
* We have a useless 40KB swap partition, which the x86image plugin
insists on creating for us. Again 40KB is the minimum size that
`mkswap` will allow. It's possible to override or modify the
x86image plugin to avoid swap altogether but I'm not sure of the
best way to proceed.
There are a few dependency cleanups in the bsp-generic stack; previously
we'd build the whole 'foundation' stack which took ages and wasn't
needed at all.
