Remove '-Werror -Wmissing-progress -I./include $(CFLAGS_xeninclude)',
those flags are already added via "libs.mk".
Flag "-I." isn't needed, we just need to fix the #include of
"xg_core.h" as this header isn't expected to be installed.
Make use of "-iquote" instead of '-I' for double-quote included
headers.
Also, regroup the CFLAGS into the same place in the makefile.
