            Bug ID: 52116
           Summary: The --print-multiarch option outputs a target triple
                    new in llvm / clang version 13 which seems at odds
                    with gcc

The new --print-multiarch option to clang outputs a target triple which seems
at odds with gcc's behavior and documentation.

The clang-13 documentation says:

-print-multiarch, --print-multiarch

Print the multiarch target triple

The gcc 11.2.0 documentation says:

-print-multiarch

Print the path to OS libraries for the selected multiarch, relative to some lib
subdirectory.

It is unclear to me the rationale for the clang-13 behavior. GCC outputs
nothing for this option, and clang outputs a target triple. Why the change in
clang-13?

This change breaks the configuration of recent Python builds using clang as the
compiler.
