BuildSystem: darwin

- made Xcode external targets consistent for each configuration.
- shunted terminal NAME=VALUE vars through xcodebuild.
- folded macosx/module.xcode shunt functions into single.
- added new report target to show a single var; eg: make report.var NAME=GCC.gcc .

BuildSystem: darwin ppc
- fixed configure on ppc host: correctly identify native architecture.
- fixed configure to be more resilient when svn probes fail.
- fixed configure to show error output for svn probes.

BuildSystme: xcode
- added external target 'external' to represent 'all things in external system'
  which is slight more than what 'libhb' might represent.
- added doc section Building.osx: External Targets .
