--- Comment #5 from H.J. Lu <hjl.tools at gmail dot com> ---
I have

[hjl@gnu-skx-1 gcc-32bit]$ ls /usr/local32/bin
addr2line  as       dwp      gprof  ld.bfd   nm       objdump  readelf  str=
ings
ar         c++filt  elfedit  ld     ld.gold  objcopy  ranlib   size     str=
ip
[hjl@gnu-skx-1 gcc-32bit]$=20

and

PATH:=3D/usr/local32/bin:$(PATH)

in Makefile.  I can bootstrap i686-linux gcc with

$ CC=3D"cc -m32 -fno-lto" CXX=3D"g++ -m32 -fno-lto"
RUNTESTFLAGS=3D"--target_board=3D'unix'"
/export/gnu/import/git/sources/gcc/configure --enable-cet
--with-demangler-in-ld i686-linux --prefix=3D/usr/gcc-11.0.0-32bit
--with-local-prefix=3D/usr/local --enable-gnu-indirect-function
--enable-clocale=3Dgnu --with-system-zlib --with-target-system-zlib
--with-fpmath=3Dsse

on Linux/x86-64.=
