Your should store the downloaded config file definitely as '.config' instead of '.config.old' (there is only
the way .config --> .config.old and not the other way round in buildroot)...

Same here with a fresh installed openSUSE Tumbleweed x86_64 without 32-bit support packages installed.

Until commit ec54092c916440501006bfa51a820eb953100510 ('toolchain-external-custom: new package'), or with
2016.11.3 the same config gives the following error instead:

[...]
Cannot execute cross-compiler '.../host/opt/ext-toolchain/bin/x86_64-ctng_locales-linux-gnu-gcc'
make[1]: *** [package/pkg-generic.mk:209: .../build/toolchain-external/.stamp_configured] Error 1
make: *** [Makefile:16: _all] Error 2

Maybe the toolchain definition should select BR2_HOSTARCH_NEEDS_IA32_LIBS?

Regards,
Peter
