Can you:
   s390*-*-linux*)
-        if test x$ac_cv_sizeof_void_p = x4; then
-                UNSUPPORTED=1
-        fi
in libsanitizer/configure.tgt and retry?  As I said on the mailing list, I
don't have any longer a way (at least not easy) to test 31-bit s390, which is
why I haven't enabled it because I couldn't test it.
If it works, then those 3 lines should be dropped.
If it doesn't work, we'll need to figure out something (such as extending the
asan_shadow_offset hook so that target can signal to toplev.c the lack of asan
support even in a different way than having the hook NULL.  Either through a
magic value, or extra argument).
