link order is wrong here: the list of -l should come after the list of
.o, and if you do that, you will not need to repeat the list of -l.

Your problem is that -lnative is missing in the list of -l you repeat,
but it is better to put the result of xeno-config --xeno-ldflags after
the list of .o (if you are using built-in makefile rules, this means
puttin this in the LOADLIBES variable instead of putting it in LDFLAGS),
and remove the repetition.
