I did:

RUNTESTFLAGS="--target_board 'unix{-m32}'" CC="gcc -m32 -fno-lto
-fcf-protection"
 CXX="g++ -fno-lto -m32 -fcf-protection" /exp
ort/gnu/import/git/gitlab/x86-binutils/configure \

i686-linux \
--enable-plugins --disable-gdb --disable-gdbserver --disable-libdecnumbe
r --disable-readline --disable-sim --with-sysroot=/ --with-system-zlib \
--prefix=/usr/local \
--with-local-prefix=/usr/local
configure: WARNING: you should use --build, --host, --target
checking build system type... i686-pc-linux-gnu
checking host system type... i686-pc-linux-gnu

pkg.m4 should handle the system pkg-config, broken or not.
