Bug#1072673: qttools-opensource-src: uses LLVM 15 which is being removed

[Emilio Pozuelo Monfort]

Source: qttools-opensource-src
Version: 5.15.8-2
Severity: important

Hi,

qttools-opensource-src is building with LLVM 15, which is going to be
removed soon. Please switch to a newer version (such as 17), or ideally
use the default version, which may be more suitable/stable these days.

Cheers,
Emilio
