By mistake on new installation I untar wrong: stage-3  x86_64 instead of
i686

during kernel compiling I got:
cc1: error: CPU you selected does not support x86-64 instruction set

Is it possible to untar new stage-3 (i686) over current one, or I need
to delete all the folders?

After selecting stage-3 (i686) I still get the same error message when
trying to compile kernel:

CC      scripts/mod/empty.o
cc1: error: CPU you selected does not support x86-64 instruction set
make[1]: *** [scripts/Makefile.build:266: scripts/mod/empty.o] Error 1
make: *** [Makefile:1137: prepare0] Error 2

The CPU I have:
AMD FX(tm)-8150 Eight-Core Processor

Isn't this a 64-bit CPU?
If you boot using a 64bit live-image (the gentoo-admin ISO as an example), you
should be able to actually use 64bit.

I'm confused as well, setting from make.conf on this CPU with previous
kernel was:
CHOST="x86_64-pc-linux-gnu"

As Joost says, maybe you can try boot from a 64bit install image to test that.

If you can, you may re-install your system to use 64bit.

Only a little chance that your cpu has some problem with x64 module.
