The change aims to make spark binaries launch properly when symlinked, not
just to avoid setting `SPARK_HOME`.
As of current master, ```SPARK_HOME``` value is overwritten in launchers by
a
```
export SPARK_HOME="$(cd "`dirname "$0"`"/..; pwd)"
```
which is generically wrong and does not work for a symlinked set-up.
This behaviour prohibits proper ( = with alternatives)
installations/packaging.
So, if 'resolve this as wont-fix' refers to the issue, I beg to differ
(this discussion should rather be moved to the ticket then).
If it refers just to the change suggested, I don't protest it.
