Various changes post sorting out some of the issues regarding task ordering.

test0 cannot be the first task in the list as it must have a prior physical_base.lds in order to create test_exec_linker.lds.
mm0 appears to have to precede fs0 for the tests to execute on start.  This should be considered a bug.
