Having some uniform turnkey script to build an i686 chroot on an x86_64
box as part of devtools would be useful.
I just noticed today that in setting up my chroots, I had replaced my
x86_64 in makepkg.conf with i686, but not replaced the x86-64 which
occur in CFLAGS and CXXFLAGS. If others have done similar things, it
might result in buggy or suboptimal packages.
It would at least be nice of someone who knows a lot about building in
chroots describes in detail what must be done for i686 chroots in x86_64
in the wiki page, just in case there are important details I or others
