This built failure is because the toolchain version you used is not
supported the latest intrinsic function/macro.
We are sending the latest patchset now and we expect the whole new
features will be supported in gcc8.0.0 and binutil2.31+.

If you'd like to get these new features of toolchain, you may use the
github version.
This is the built-script repo. https://github.com/andestech/build_script.git
I've taken the gcc-6.3 sources from there, and updated them to gcc-6.4.0
in order to build a nds32le-linux toolchain based on the same version as
the other ones.

Unfortunately neither the usual binutils-2.29.1 nor your binutils worked
for me, but I eventually managed to get a build using the binutils-2.30
release.

With this, I could build a mainline kernel with a couple of warnings,
but an 'allmodconfig' build still failed.

Guenter, can you try my binary from
www.kernel.org/pub/tools/crosstool/files/bin/x86_64/6.4.0/x86_64-gcc-6.4.0-nolibc-nds32le-linux.tar.xz
?
defconfig and allnoconfig are ok. allyesconfig results in a linker core dump,
unrecognized instruction warnings from the assembler, and various vdso
related build errors.
