Add --enable-ubsan
This adds --enable-ubsan to gdb's configure. By default it is enabled
in development mode, and disabled otherwise. This passes both
-fsanitize=undefined and -fno-sanitize-recover=undefined to
compilations, so that undefined behavior violations will be sure to
cause test failures.
