nextpnr-ice40 gives a better fMAX for this design (by about ~9Mhz for
me: ~59MHz -> ~68MHz) and is The Way Of The Future.

This touches up the Makefile so that it:
- uses $@, $< and $^ in more places for brevity and robustness (typo
guards, etc)
- tracks dependencies slightly better (e.g. .pcf file changes weren't
tracked before)

This fixes the icestorm script to query yosys-config itself for the
right data directory. Not only does this fix installs where yosys was
not installed into /usr/local, it also ensures Icarus picks up a data
directory consistent with the version of yosys that you're using.
