You seem to miss the very important fact that the variable namespace in
Buildroot is global. So when you change TARGET_CONFIGURE_OPTS here you
change it for *all* packages, not just yours.

What are you trying to do here? If you want to override the CFLAGS just
for Xen, you should do:

XEN_CONF_ENV = \
	CFLAGS="$(TARGET_CFLAGS) your custom cflags"

Best regards,

Thomas
