Description

Experimentally, we've seen some vexing behavior from dmake that most often manifests itself when performing a multi-proto build. Specifically, we saw that dmake sometimes doesn't descend into the subdirs of cmd/acpi, but does descend into common. In theory this should always happen because in cmd/acpi/Makefile, $(SUBDIRS) depends on common which depends on FRC. Because we should always in theory rebuild common due to FRC, we should also therefore rebuild the $(SUBDIRS).

For some reason, this isn't happening. In addition, whenever debugging with the -d or -dd flags is enabled, dmake then of course does the right thing. In the interim, to stop breaking folks who are using the multi-proto build, we should add an extra FRC dependency on the $(SUBDIRS) target.
