exiv2 added -fcf-protection, which is not supported on either ARM or PPC.
1ea63ccb34 fixes that but only for ARM.
Merge this commit and add modify it to also fix PPC. This is likely the wrong approach, since -fcf-protection seems to be available only on amd64, but this is the approach that upstream chose.
