If you want to run without chroot command then no conffile inside the
chroot will have any effect. Logicaly it can only mean outside the
chroot.

Please ignore that and instead just "apt-get install libc6-i386". That
package will provide the linker and a 32bit libc that will be current.

You have to get that library. The package is even names libstdc++5.

That is what you get for not using debs. rpms don't have Debians
