Subject: [PATCH] tests: Fix compiler-tests.sh for no build args passed case

When a user ran "tests/compiler-tests.sh" without passing any arguments,
the compiler tests would fail with:

```
scons: Reading SConscript files ...
Error: No existing build directory and no variant for /gem5
```

However, when passed with arguments, such as:

```
./tests/compiler-tests.sh -j6
```

the tests passed.

The fix for this is to merge the "$build_out" and "$build_args" into a
single string when executing the docker. I do not know exactly why this
works, but it does fix the error.
