code generator in makefiles

[Havoc Pennington]

Hi,

glib-genmarshal is really hard to use in Makefile.am; in fact I usually
give up (see glib/Makefile.am) 

Would it work if dbus-binding-tool checked source-target timestamp
*inside dbus-binding-tool*, so you would just unconditionally run dbus-
binding-tool in all-local or something and it would do the right thing?

Related topic, we need a way to get at dbus-binding-tool as a pkgconfig
variable as for glib-genmarshal
