yes, we literally want exactly what is used in coriolis2 cmos Makefile,
with as few deviations from that as possible.

so, no hard-coded macros

because all these hard-coded macros go into user.d/{yourloginid}-user.mk
and they are pulled in via mk/design-flow.mk

obviously, substitute s/m65s/part_sig_add

the way that it looks like the coriolis2 makefile system works is,
it extracts the "top" name from the make "things".

so we do not want "top" hard-coded into the Makefile, either, or
YOSYS_TOP=/tmp/yosys_top, although i appreciate that it gets things
