+dnl A test that is configured out compiles down to "return 77", the automake
+dnl skip code, and so does the main() that forwards to it. Apple's linker folds
+dnl the two identical bodies together, then writes LC_MAIN entryoff 0, so the
+dnl binary starts executing at the Mach-O header and dies with SIGILL instead
+dnl of skipping. Turn the folding off where the linker understands the flag;
+dnl GNU ld rejects it and is unaffected.
