Changes in commit v3.4.0-rc1~124^2~1 (cmFindProgramCommand: Re-implement search using more flexible approach, 2015-09-01) did not preserve the behavior of looking for the given name with no search path at all. Fix this and add a test case covering finding an absolute path with no search directories.
