There is an arch/ tree under tools.  This contains some useful stuff, to
make that available, add it to the -I flags.  This requires $(SRCARCH),
which is provided by Makefile.arch, so include that..

There still aren't that many headers so also just smush all of them into
SHARED_DEPS instead of starting to do any header dependency hocus pocus.
