dmd build instructions from source don't work anymore

[Timothee Cour via Digitalmars-d]

NOTE:
I had 'export CC=gcc' in my environment, leading to this behavior (ie
worked fine until 'Merge pull request #3970 from yebblies/idgend2', and
breaks after that pull request is merged).

If I 'unset CC' it works. But IMO it should work even when user has set CC
(or at least provide a better error message)
Also I notice CC is set to 'g++' in posix.mak which is untypical (instead
of gcc for example)

Other users could face the same issue which is hard to debug.
