Android arm64 and x86_64 builds now require 16KB page size alignment in native binaries, this includes FFmpeg. When running patchelf on the binaries, it will implicitly re-align the affected sections to 4KB page size. This patch solves this by using the --page-size flag for patchelf, only for the builds that require it. Pick-to: 6.11 6.10 6.8 Fixes: QTBUG-142332 Change-Id: Iba88bf702fd075d2b4432d9cde94f779b14de52f Reviewed-by: Assam Boudjelthia <assam.boudjelthia@qt.io>
