    Add support for a saving build objects in a separate directory. · f9328639

    Modifications are based on the linux kernel approach and
    support two use cases:
      1) Add O= to the make command line
      'make O=/tmp/build all'
      2) Set environement variable BUILD_DIR to point to the desired location
      'export BUILD_DIR=/tmp/build'
    The second approach can also be used with a MAKEALL script
    'export BUILD_DIR=/tmp/build'
    Command line 'O=' setting overrides BUILD_DIR environent variable.
    When none of the above methods is used the local build is performed and
    the object files are placed in the source directory.
