Thanks for the heads up. Actually I consider this as a bug in the Debian packaging, because optimization flags are supposed to be taken from dpkg-buildflags. This is actually the case for most architectures, but on ppc64el the -O3 flag is indeed taken from upstream build system, and this should ideally be changed. -- ⢀⣴⠾⠻⢶⣦⠀ Sébastien Villemot ⣾⠁⢠⠒⠀⣿⡁ Debian Developer ⢿⡄⠘⠷⠚⠋⠀ https://sebastien.villemot.name ⠈⠳⣄⠀⠀⠀⠀ https://www.debian.org
