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)
