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().
