A grub for xen can be built with CPPFLAGS="-I/path" ./configure, which
has the benefit that CPPFLAGS gets automatically included in the
Makefiles. There is no need for a private makefile variable, the xen
headers are equal to headers for other optional components.
For some commands the cppflags have to point to POSIX, otherwise
stdint.h will not be found. Previously it was loaded unconditionally
from /usr/include.
