binutils-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 binutils-config runs and are meant for manual testing. Undocumented for now.
