+`--enable-ubsan'
+     Enable the GCC undefined behavior sanitizer.  By default this is
+     disabled in GDB releases, but enabled when building from git.
+     The undefined behavior sanitizer checks for C++ undefined

+     Enable (i.e., include) support for unit tests when compiling GDB
+     and GDBServer.  Note that if this option is not passed, GDB will
+     have selftests if it is a development build, and will *not* have
