root@tentacle:/mnt/gentoo# cat etc/make.conf # These settings were set by the catalyst build script that automatically # built this stage. # Please consult /etc/make.conf.example for a more detailed example. CFLAGS="-O2 -mtune=i686 -pipe" CXXFLAGS="${CFLAGS}" # This should not be changed unless you know exactly what you are doing. You # should probably be using a different stage, instead. CHOST="i486-pc-linux-gnu" I haven't changed anything yet (tarball stage3-x86-2007.0.tar.bz2). Reproducible: Always Steps to Reproduce: 1. download stage tarball 2. extract 3. look at gentoo's /etc/make.conf Actual Results: -mtune set to 686 and system very probably compiled with wrong mtune Expected Results: -mtune set to 486 before the user changes it to his processor type
-mtune=anything is perfectly acceptable as the -march is still set to the lowest (like i486)
