This is a bit too aggressive, IMO. E.g. `-g1` or `-gmlt` works just fine.
The warning should apply only to full debug info. You should probably move the
code below to where we check DIKind and issue the warning only if `DIKind ==
FullDebug`.
Then there's a question of whether the warning is useful in general. E.g. in a
large project where optimization and debug options are controlled globally, the
users will all of a sudden start getting the warnings. The builds with -Werror
will be broken and the users will have no easy way to deal with that.
