Enable more architectures with stack direction is downwards

In fact, there is one debian patch prototype to improve the situation:

...
 if test "${with_stack_direction}" = unknown; then
-  AC_TRY_RUN([ void inner (char *foo) { char bar; exit (!(foo >= &bar)); }
-	       void main () { char foo; inner (&foo); } ],
+  AC_TRY_RUN([
+#include <stdio.h>
+#include <string.h>
+int inner(int *a) { int b; char sa[50], sb[50];
+  sprintf(sa, "%049llu", (unsigned long long)a);
+  sprintf(sb, "%049llu", (unsigned long long)&b);
+  return strcmp(sa, sb); }
+int main() { int x; return inner(&x) < 0; } ],
    [AC_MSG_RESULT([downwards])
     with_stack_direction=-1],
    [AC_MSG_RESULT([upwards])
...

If this makes sense, I can update it here.
