gcc-config: add build-time and runtime switches to disable native symlinks
We have two knobs here: 1. Build-time knob USE_NATIVE_LINKS to set a default, defaults to 'yes' (existing behaviour) 2. Run-time --enable-native-links / --disable-native-links knobs. These are not persistent across gcc-config runs and are meant for manual testing. Undocumented for now.
