Trying to build openmp 15.0.2 with clang 15.0.1, but this happens whenever clang built on i686 is used. This isn't an issue on x86_64 or armv7l.

CMake Error at /usr/local/share/cmake-3.24/Modules/CMakeTestCCompiler.cmake:69 (message):
The C compiler

is not able to compile a simple test program.
It fails with the following output:

It gets much further with clang 14.0.6, but I think we need clang 15.x to build the llvm 15 version of openmp...
