  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.
