Adhemerval Zanella 82fd7314c7 powerpc: Remove backtrace implementation ...

The powerpc optimization to provide a fast stacktrace requires some
ad-hoc code to handle Linux signal frames and the change is fragile
once the kernel decides to slight change its execution sequence [1].

The generic implementation work as-is and it should be future proof
since the kernel provides the expected CFI directives in vDSO shared
page.

Checked on powerpc-linux-gnu, powerpc64le-linux-gnu, and
powerpc64-linux-gnu.
