[PATCH 1/3] um: Run host archheaders, allow use of host generated headers

From: H. Peter Anvin
Date: Mon Dec 05 2011 - 20:06:19 EST


From: "H. Peter Anvin" <hpa@xxxxxxxxxxxxxxx>

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.
