Hi Gergely,

What is the version of uclibc-ng ? did you try with the latest 1.0.2 ?

The powerpc issue has been fixed for Buildroot's internal toolchains by [1] but
it's not for (old) external toolchains. However, an exception in autobuilders
can be added for these toolchains.

This change enable ptrace for powerpc and disable ptrace for xtensa.
It would be good if it can be done in a separate patch.

Best regards,
