Although it is difficult to use, we can remove the default libraries with `-nostdlib`. This is what I am using when I am building different configurations of libc++abi and libunwind on Linux.
For your long-term plan on the default standard library, I agree that we should select the default standard library according to the environment. However, I am still concerning the overloaded meaning for `-l` options. For example, what will happen if the users specified `-lunwind` when they are mean to link with libunwind from Savannah? The libunwind from Savannah does not include C++ level 1 unwinding library by default.
