Can you test anything that depends on a previous test? I guess you mostly work around it by having a separate stage for checking compiler flags.

BTW: for something far uglier I recently happened to post: https://github.com/openucx/xpmem/pull/80

probably yes but the Makefile might need the dependencies made explicit so it doesn't run the depending test before its dependent header has been generated.

autoconf already has a cache feature , see --config-cache, --cache-file, etc.
One can also use ccache.

Well, ccache skips caching of autoconf ("conftest") checks.

Make's core functionality is generating files that depend on other generated files, so that would just naturally work. However, it's a bit trickier to get it to figure out by itself that a test uses the compiler flags and therefore depends on checking the compiler flags (as opposed to the developer indicating the dependency).
