driver: reject -shared in cc and ld (not yet supported)

cc -shared and ld -shared now error immediately with "creating
dynamic/shared libraries is not yet supported".  build-lib -dynamic
and build-exe -shared were already rejected; this closes the remaining
two entrypoints that silently fell through to an incomplete linker stub.
