ENH: Fix optional use of relative paths. 

These changes refactor cmLocalGenerator methods Convert and
ConvertToOutputForExisting to support references inside the build tree
using relative paths.  After this commit, all tests pass with Makefile
generators when relative paths are enabled by default.  See issue #7779.
