OK, external toolchain has older MUSL, it's without 
f67b3c17 ("sys/fanotify.h: update for linux v5.1")
from v1.1.23. => need to fix autoconf in LTP for latest musl release.

I didn't realized that there could be more MUSL versions,
next time, I'll check with utils/test-pkg
support/config-fragments/autobuild/*musl*
and also for internal toolchain (somehow wasn't able to use 
support/config-fragments/autobuild/*internal-*musl* with utils/test-pkg).

Kind regards,
Petr
