Subject: [PATCH] Makefile: Add implicit rule for STANDARD_TESTS

To confirm that the Makefiles works as expected after this patch, the
list of executed commands before and after is compared:

Before:

```
make --dry-run > ../dockcross-make-baseline
make test --dry-run > ../dockcross-make-test-baseline
```

After:

```
make --dry-run > ../dockcross-make-current;
make test --dry-run > ../dockcross-make-test-current

for target in make make-test; do
  diff ../dockcross-$target-current ../dockcross-$target-baseline > /dev/null 2>&1
  [[ $? == 1 ]] && \
    echo "" && \
    echo "Error: Problem with '${target}' target: Dry-run output before and after this commit do not match."
done
```
