Revert "Pass preprocessor options to C compiler when building foreign C files (#16737)"
This reverts commit 1c18d3b41f897f34a93669edaebe6069f319f9e2.
`-optP` should pass options to the preprocessor, that might be a very
different program to the C compiler, so passing the options to the C
compiler is likely to result in `-optP` being useless.
Fixes #17185 and #21291
