dir: Explicitly 'make all' in src/dir/test
Currently, we 'cd test' and then just run 'make', which makes the
first target specified in the Makefile. On some platforms (FreeBSD),
this results in 'make' trying to build '%.c', which of course we
cannot do, since that's a pattern rule, and so 'make' fails.
To fix this, just 'make all' explicitly, to make the intended targets
in src/dir/test.
