OK, step1b is still problematic:

At least we know, that once we solve this problem, we can remove
0002-kernel-controllers-Link-with-libfts-explicitly-on-mu.patch

Please, how to reproduce this build locally? Is it:
. oe-init-build-env
TCLIBC=musl bitbake ltp

Or do I need to put something into config files conf/local.conf
or conf/bblayers.conf ?

I need to double check if musl-fts is really built and whether the order of
-lfts is correct. But all this has been solved even for static build for Buildroot,
so I guess it's some issue related to openembedded. Unfortunately, I'm not much
experienced in openembedded (stepped in, because nobody else has updated LTP
package yet).

Khem, any idea, what can be wrong?

Kind regards,
Petr
