Johannes Bornhold 7672c68ed7 dmd: Avoid depending on gcc for the darwin build (close #11949)
Adding stdenv.cc into the PATH, also setting CC, so that on Darwin
clang will be used by default. Still allowing to use an existing value
of CC if it is set already.

Replacing __inline_isnanl with __inline_isnan on darwin since the former
one was not defined.
