Yes, the CC setting is used to invoke the linker.

Cross-compiling druntime/phobos is possible but untried. You
could try to setup host and target compilers in CMakeList.txt or
you could build a small script to compile all .d modules into a
library. There is no out-of-the-box solution.
(Currently I build ldc on an ARM box and avoid the cross
compiling scenario.)
