+Subject: [PATCH 3/4] Fix CUnit test for cross-compilation
+
+The current test in configure.ac for CUnit uses AC_TRY_RUN, which
+doesn't work in a cross-compilation context, because we can't run on
+the build machine the binaries that are built for the target. In
+addition, the current logic assumes CUnit is available when the
+AC_TRY_RUN test cannot be used (e.g in a cross-compilation case).
+
+Since we actually don't care about *running* but only about testing
+whether a simple program include the CUnit header file and linking
+against the cunit library works, simply use AC_TRY_LINK() instead of
+AC_TRY_RUN().
