The reason I'm picking on the test files and not the message Creating blah because of (1) file is because it has the logic in TestFilesCompilation.gmk compiles each individually.
Adding a message at the end of it like:

    +  $$(call LogWarn, Creating $$($1_OUTPUT_DIR)/support/ from $$(words \
    +               $$(filter-out %.vardeps, $$($1_FILTERED_FILE_LIST))) file(s))

comes out whether anything compiled or not, which nobody wants.
Unless you can pass status back from this 'foreach' loop.  I guess I'm stuck.
