The problem with cross compilation isn’t the compiler, it’s the build system. See eg the autoconf, which builds test binaries and then executes them, to test for availability of strcmp(3).

I feel like there should be a more sane way to test for the availability of strcmp than to build and run a whole executable and see if it works.

The sheer number of things autoconf does even for trivial programs has always been baffling to me.
