build/autotools: depend "config-extra.h" on "config.h"
"config-extra.h" is really just like "config.h", except it works around some
limitations of autoconf.
If we depend on "Makefile", any changes to "Makefile.am" will cause a full
rebuild. We want to avoid that.
Instead, depend on "config.h". That one only changes when configure runs
again. And that's the better dependancy, because "config-extra.h" is
generated based on informations generated by configure (despite being
generated by "Makefile").
