+dnl Divert AC_TRY_COMPILER to make ac_cv_prog_*_works actually cached.
+dnl This will allow to just skip the test when python configure has set
+dnl the value for us. But since ac_cv_prog_*_cross is calculated at the same
+dnl time, and has a different meaning as in python configure, we only want to
+dnl use its value to display whether a cross-compile is happening. We forbid
+dnl configure tests that would rely on ac_cv_prog_*_cross autoconf meaning
+dnl (being able to execute the product of compilation), which are already bad
+dnl for cross compiles anyways, so it's a win to get rid of them.
