[Libunwind-devel] [PATCH 0/7] Fixup the PowerPC (64 & 32 bit) builds.

[Cody P Schafer]

This patchset fixes a few errors & warnings in building libunwind for powerpc.

Build failures occured primarily due to
 - attempts to build the 32bit powerpc code as 64bit and vise versa.
   - solved by changing how configure checks for a 64bit compilation
 - libunwind-coredump lacking ppc support.
   - solved by making coredump an optional component and disabling it on 
everything but x86*.
