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

make.conf
COMMON_FLAGS="-march=native -O2 -pipe"
#COMMON_FLAGS="-O2 -march=i686 -pipe"
CFLAGS="${COMMON_FLAGS}"
CXXFLAGS="${COMMON_FLAGS}"
FCFLAGS="${COMMON_FLAGS}"
FFLAGS="${COMMON_FLAGS}"
CPU_FLAGS_X86="mmx mmxext sse sse2 sse3"

SOLVED:
One need to disable "64-bit kernel" in the root of the menuconfig.

AMD FX-8150 should support x86-64 according to the it data, very confused.
