Didn't look much into the patches, so I'm not sure if this includes both the
configuration and build system for Linux, but the kernel's build system might
provide a more robust and flexible build system.

Which reminds me of some older discussion about having a single QEMU binary able
to emulate a system with CPUs from different architectures (with a future^2
version of qom'ified CPUs).

Such fine-grained compilation would deviate even more from that goal (assuming
it's a goal).
