gcc-6 uses -no-pie instead of -nopie (the latter doesn't work), and strip-flags should allow -no-pie. steps to reproduce: 1. install gcc-6 with USE=pie 2. try to compile an application that uses strip-flags with CFLAGS="-fno-PIE" LDFLAGS="-no-pie"
should be fixed with: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=f461e9f8576ab71a998b580095a8de1530cdbd35
