If you can tell (1) that we're compiling java and (2) that this is
a JNI function, then targetm.insert_attributes can do this.  Except
that jc1 does not, at present, call decl_attributes.

The first point can be handled with 

	strcmp (language_string, "GNU Java")

    Not ideal, really.  Should promote the nonsense in dwarf2out.c
    gen_compile_unit_die to be a proper lang thingy so it'd be more like

	lang_hooks.dwarf2_language() == DW_LANG_Java


No idea what to do about the second point.  Looks like you're
supposed to check

	METHOD_NATIVE(decl) && flag_jni

but this would only compile inside the Java front end.

So I guess a macro is all we've got left.
