build: support waveform debug using opensource tools

Browse Source 
VCS is not free. Neither is the vcd format.
Fortunately, verilator and gtkwave ARE free ... and faster too.

This patch adds targets:
	run-regression-tests-fst
	run-asm-tests-fst
... which create opensource-compatible fst waveforms for gtkwave.
