    xen: append EXTRA_CFLAGS_XEN_CORE to CFLAGS
   
    Allow a user to supply extra CFLAGS via the EXTRA_CFLAGS_XEN_CORE
    environment variable for hypervisor builds. This is not a
    configuration that is supported but is only aimed to help support
    testing and troubleshooting when you need to make changes.

 This variable can be used to use DIR/include and DIR/lib during build.
 This is the same as PREPEND_LIB and PREPEND_INCLUDES. APPEND_LIB and
 APPEND_INCLUDES= will be appended to the CFLAGS/LDFLAGS variable.
