Summary:
This makes it more obvious why infer would force a path to be absolute since we
base that decision on the resolved path. For instance:
```
$ mkdir foo
$ cd foo
$ ln -s ../examples goo
$ infer -- clang -c goo/hello.c
[...]
/home/jul/infer/examples/hello.c:14: error: NULL_DEREFERENCE
```
We see that the path is outside of the current directory clearly, whereas
before infer would report on "goo/hello.c".

Summary:
Seems like we cannot run 2 instances of Buck in parallel even when one uses
buck-out/ and the other buck-out/foo/.
