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.

* macho.c: New file.
* filetype.awk: Recognize Mach-O files.
* Makefile.am (FORMAT_FILES): Add macho.c.
(check_DATA): New variable. Set to .dSYM if HAVE_DSYMUTIL.
(%.dSYM): New pattern target.
(test_macho_SOURCES, test_macho_CFLAGS): New targets.
(test_macho_LDADD): New target.
(BUILDTESTS): Add test_macho.
(macho.lo): Add dependencies.
* configure.ac: Recognize macho file type. Check for
mach-o/dyld.h. Don't try to run objcopy if we don't find it.
Look for dsymutil and define a HAVE_DSYMUTIL conditional.
* Makefile.in: Regenerate.
* configure: Regenerate.
* config.h.in: Regenerate.
