Using -ftree-loop-distribute-patterns and -gno-variable-location-views
in the python feature test when building with clang-16 results in:
16 80.04 clearlinux:latest : FAIL clang version 16.0.1
clang-16: error: unknown argument: '-gno-variable-location-views'
clang-16: error: unknown argument: '-gno-variable-location-views'
clang-16: error: optimization flag '-ftree-loop-distribute-patterns' is not supported [-Werror,-Wignored-optimization-argument]
clang-16: error: optimization flag '-ftree-loop-distribute-patterns' is not supported [-Werror,-Wignored-optimization-argument]
error: command '/usr/sbin/clang' failed with exit code 1
Noticed when building on a docker.io/library/clearlinux:latest container.
