Small quality-of-life fixes

[FrancescoConti]

1. enable compilation without cleaning by overwriting the (anyways broken!)
   modelsim.ini, etc. files on symlink creation
2. work out-of-the-box on non-ETH machines by not defining the QUESTA
   env var
3. make run dependent on $(TARGETS) being built

The changes looks good. However, as we bump the runtime for the cluster the TCL scripts used to run the simulation must be tweaked. In particular, in this line and this line the APP variable must be set to test/test since we are already executing in build.

Does it break if we merge?

[ricted98]

We should not break the cluster as long as we do not update the commit we are referencing in the submodule for the pulp-runtime. And then we need to update the TCL scripts.

I think it's easier to fix these small things directly in this branch before merging the PR. I will take a look

[ricted98]

We might have to set up a dedicated PR on the cluster in parallel to implement the fixes I suggested before.

It's better to check if /etc/iis.version exists to determine whether it is an ETH machine that doing some hostname grepping thing
