Replace usage of stdenvNoCC.

- For Linux, the real fix is `hardeningDisable` of "fortify";
- For macOS, the real fix is setting the C and CXX compilers in `desktop/build.sh` as well as disabling CMake install step;
- Unfortunately for iOS we still need stdenvNoCC (or find a way to use GNU's ld instead of Apple's)
