[PATCH 01/10] tools: improve vma test Makefile

[Lorenzo Stoakes <lorenzo.stoakes@oracle.com>]

Have vma.o depend on its source dependencies explicitly, as previously
these were simply being ignored as existing object files were up to date.

This now correctly re-triggers the build if mm/ source is changed as well
as local source code.

Also set clean as a phony rule.
