lang/clang fails to build (NetBSD 9/aarch64)

Hi!

During my usual pkg_rolling-replace run, I noticed that lang/clang 
(14.0.6) now fails to build. I have a NetBSD-9 userland on a Pinebook Pro 
(thus evbarm-aarch64):

/usr/pkgsrc/lang/clang/work/clang-14.0.6.src/lib/Interpreter/IncrementalParser.cpp: 
In lambda function:
/usr/pkgsrc/lang/clang/work/clang-14.0.6.src/lib/Interpreter/IncrementalParser.cpp:56:28: 
error: 'state_not_recoverable' is not a member of 'std::errc'
                 std::errc::state_not_recoverable,
                            ^~~~~~~~~~~~~~~~~~~~~

Any ideas? I assume this is compiled with the system gcc (7.5.0), is that 
too old now to build clang?
