You need the "ports" addon. Available in the "C library" sub-menu.

That's wrong: for the C library, there is no idea of "target". You only
have to care about:
- the machine the C library is _built_ on, set with --build=...
- the machine the library will _execute_, set with --host=...

The idea of "target" is only meaningful for the compiler (and assembler...),
and means:
- the machine the tools _generate_ code for, set with --target=...

Alternatively, for a debugger or a disassembler, the "target" is described
as:
- the machine the tools _interpret_ code of, also set with --target=...

I guess the answer is above :-)
