depends: Issue cross compiling for macOS on Debian Buster #16052
Description
Using a debian:buster-slim Docker container, available here, doing a depends build for x86_64-apple-darwin14, cctools bombs out with the following in config.log:

See `config.log' for more detailsCross-compiling with a debian:stretch-slim container works file, so my assumption is a change in Busters newer GCC (8.3.0) has broken our older Clang (3.7.1).
A a similar issue appeared in Clang previously, which produced similar output, and was resolved in LLVM here.
