In this case it is actually for SIMH itself and not the front panel (that
can come later), so it is using the standard makefile. I don't have the
output to hand, but it looked to me like it was able to compile but could
not link. I don't think SDL2 is installed properly and I don't know how that
is supposed to be done.
