This is very confusing. “stdenv” is created from the parent stage so
pkgsTargetTarget.stdenv.cc is a compiler that runs /on/ host platform
and creates binaries for target platform. gfortran on the other hand
is not special cased like stdenv, so the equivalent to
pkgsTargetTarget.stdenv.cc is pkgsHostTarget.gfortran.
I’ve rewritten this to be a little less confusing, “pkgsHostTarget” is
equivalent to “pkgs” so it is unneeded. All that is left is
“pkgsTargetTarget.stdenv” which is equivalent to
“targetPackages.stdenv”.
