canlock fails to cross build from source, because it uses AC_RUN_IFELSE
to determine whether memset_s is available. For simply checking
availability and checking whether the prototype matches,
AC_COMPILE_IFELSE is sufficient. The attached patch adapts the check and
thus makes canlock work with cross compilation. Please consider applying
it.
