I compared the test result on native arm and aarch64 gdb, there is no
regression either.

OK, that is fine to me. After we start to build GDB in C++ mode on some
hosts, I hope we don't have to support both modes too long. According the
c++ conversion in gcc, ENABLE_BUILD_WITH_CXX on configure was added in
2009, and was removed on 2012.
