Thanks, pushed.

But note that it broke the buildbot:
https://builder.wildebeest.org/buildbot/#/builders/53/builds/2

Actually it was already broken, because that buildbot builder has an
gcc so old that it doesn't know about -gdwarf-5.

But it also doesn't seem to know about -gz=none.

So we'll need configure checks for that and not use -gz=none and skip
the -gdwarf-5 tests when gcc isn't able to use those options.

Cheers,

Mark
