d1339b519a libbacktrace, Mach-O : Support PowerPC archs. 
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.
	(MACH_O_CPU_TYPE_PPC64): New.
	Add compile-tests for powerpc to the Mach-O variants.

0755f573f0 libbacktrace: avoid ambiguous binary search 
Searching for a range match can cause the search order to not match
the sort order, which can cause libbacktrace to miss matching entries.
Allocate an extra entry at the end of function_addrs and unit_addrs vectors,
so that we can safely compare to the next entry when searching.
Adjust the matching code accordingly.

Fixes https://github.com/ianlancetaylor/libbacktrace/issues/44.
