stripped build.log for sys-libs/glibc-2.26-r3

I'm forced to upgrade to sys-libs/glibc-2.26-r3 (bug 637388, comment 1) but this fails at install phase due to “cannot execute binary file” for “/var/tmp/portage/sys-libs/glibc-2.26-r3/work/build-x86-x86_64-pc-linux-gnu-nptl/elf/sln”

Comparison of available sln:

$ [work]> file build-x86-x86_64-pc-linux-gnu-nptl/elf/sln
build-x86-x86_64-pc-linux-gnu-nptl/elf/sln: ELF 32-bit LSB executable, Intel 80386, version 1 (GNU/Linux), statically linked, for GNU/Linux 3.2.0, not stripped

Please provide emerge --info.

Sorry I forgot.

First, just try to manually emerge libnsl in addition to world, to give portage a hint what to do. 
emerge -uDNav libnsl world

(libnsl-0 doesnt require new glibc and is stable.)

If that doesnt help, check if your Kernel is able to run 32bit binaries! You are compiling a multilib glibc, and for that you need a kernel that can run 32bit files...

You make my day – it was the latter. Several weeks ago I've modified my kernel
configuration (too aggressive) to reduce the kernel image and must have been
dropped ‘CONFIG_IA32_EMULATION=y’.

Thank you very much for your work, advice and sorry for the noise.
