make debug does not exist?

[SigmaX]

The docs and make help both speak of a make debug and make debug_nocuda target.

Not sure these still exist. I see them as listed as .PHONY targets in carlsim/carlsim.mk, but they don't seem to actually be implemented anywhere.

Took me a minute to figure out (as a newcomer) that make release_nocuda works just fine, and that it's specifically debug and debug_nocuda that don't work.
