This causes segfaults in consumers when the stl USE flag is changed.

Oh, AFAICT nothing in the Gentoo package tree depends on tinyxml[-stl], so one solution to this would be to package.use.force the stl flag. I used `qgrep -He 'tinyxml.*-stl'` to check, the only match is games-util/desurium from 'gamerlay' and 'hasufell' overlays.
