um: Run host archheaders, allow use of host generated headers
Run the "archheaders" target for the host architecture, for architectures (like x86, now) that want to generate some of the necessary header files. Add $(HOST_DIR)/include/generated to the include path so we then pick them up. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
