This is Slackware 15.0 i586 (mostly), but I keep kernel as 64-bit.
(so, cross-compiler done by just installing binutils + gcc into /opt/
folder).

This particular failure was fixed by just deleting everything but .git
folder and re-checkout all files.

Thanks for help!

PS: gcc 7.5.0 Line I used with gcc 11.4.0:

setarch i686 .././configure --prefix=/opt/kgcc64
--target=x86_64-unknown-linux-gnu --enable-languages=c,c++
--without-headers --with-gnu-ld --with-gnu-as --disable-shared
--disable-threads --disable-libmudflap --disable-libgomp
--disable-libssp --disable-libquadmath --disable-libatomic
--disable-decimal-float --disable-libsanitizer --disable-libvtv
--disable-libitm --disable-libcilkrts  --disable-multilib
--disable-libmpx --disable-libstdcxx

same --target and --prefix was used for binutils.
