Subject: [PATCH] x86/vdso: Add arch/x86/include/uapi include path to HOST_EXTRACFLAGS

From: Oleg Nesterov <oleg@...hat.com>

Change HOST_EXTRACFLAGS to include arch/x86/include/uapi along with
include/uapi.

This looks more consistent, and this fixes "make bzImage" on my old
distro which doesn't have asm/bitsperlong.h in /usr/include/.
