This adds the PPC architecture variants for Mach-O libbacktrace. With this (as for X86 and Arm) when dsymutil is run on the binary we get a basic usable backtrace. Testsuite results on powerpc-apple-darwin9 are the same as for X86: * btest fails (TBC why) * dwarf5 tests fail because dsymutil does not handle that so far. libbacktrace/ChangeLog: * macho.c (MACH_O_CPU_TYPE_PPC): New.

Searching for a range match can cause the search order to not match the sort order, which can cause libbacktrace to miss matching entries.
