  Changed paths:
    A delta/test0_delta/Makefile
    A delta/test1_multidelta/Makefile
    A delta/test2_multidelta/Makefile

  Log Message:
  -----------
  Add Makefiles for provided "delta" tests.

Add the Makefiles for the tests that are part of the third-party "delta"
package.

I overlooked including these previously, back in October 2015 (at commit
381839f), because we usually ignore files called "Makefile".
