Issue #10655: Fix the build on PowerPC on Linux with GCC when building with
timestamp profiling (--with-tsc): the preprocessor test for the PowerPC
support now looks for "__powerpc__" as well as "__ppc__": the latter seems to
only be present on OS X; the former is the correct one for Linux with GCC.

namespace if it occurs as a free variable in a nested block. This limitation
of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
This sample was valid in 2.6, but fails to compile in 3.x without this change::
>>> def f():
... def print_error():
... print(e)
... try:
... something
... except Exception as e:
... print_error()
... # implicit "del e" here
This sample has always been invalid in Python, and now works::
>>> def outer(x):
... def inner():
... return x
... inner()
... del x
There is no need to bump the PYC magic number: the new opcode is used
for code that did not compile before.
