The toolchain is using uClibc 0.9.33.2 + the uClibc patches that we had
back in the 2013.11-rc2 release.

We have a uclibc-0020-update-ptrace.h-to-latest-from-glibc.patch that
updates ptrace.h, but it seems like powerpc doesn't use the common
ptrace.h, but its own version, and this version hasn't been updated in
uClibc master.

Comparing the uClibc powerpc ptrace.h with the one in glibc indeed
shows a significant number of differences, including the addition of
PTRACE_SETSIGINFO. Someone should cook a patch that syncs up the
powerpc ptrace.h of uClibc with the one from glibc.

Best regards,

Thomas
