- At the beginning of a build, display an 'OE Build Configuration',
  showing some important variables and their values, to make it easy
  to spot an incorrect setup.
- Change the default TARGET_ARCH and TARGET_OS to no longer be the BUILD
  versions.  It used to make sense, given the primary configuration file
  resided in the core.  Now that its in our metadata, we can change that,
  and also make the build abort with an obvious error if either are not set.
