[PATCH] test: don't use $(dir) in recipes.

[David Bremner]

According the semantics of make, the expansion of $(dir) in recipes
uses dynamic scope, i.e. the value at the time the recipe is run. This
means if test/Makefile.local is not the last sub-makefile included,
all heck breaks loose.

This was originally part of some suggested changes to Jani's folder
series, but no reason to wait for Jani and I to sort that out.
