[Qemu-devel] [PATCH 39/67] target: replace command line flags with preprocessor

[Michael S. Tsirkin]

Each target is currently built with a different set of include
directories, this is what makes it possible to pull in a separate copy
of header files depending on the target.

Replace with per-target ifdefs which are easier to understand.
