You can specify `-link-internally`, which at least works when not 
cross-compiling on Windows. There's also the `-linker` flag which 
allows you to specify which linker to use, but it still invokes 
GCC. You can use the `CC` environment variable to override the C 
compiler that is invoked for linking.

LLVM contains replacements for most of the GNU toolchain, 
although it does not have its own implementation of libc. musl 
can be used as a replacement but only on Linux.
