[Interest] update on building Qt/Linux with clang?

in my case it's not clang which crashes but the qlalr that clang produces.
For some reason it works :
- when building in debug
- when building statically

it's just the release / dynamic configuration that crashes, and I don't
know how to instruct Qt's configure to keep debug symbols for release
builds of the tools in order to get a proper stacktrace.
