'logdir' system attribute in configuration file does not work correctly

[mand35]

The behavior with the logdir handling seems to be strange. If I define the logdir option at the machine specification in reframe/settings.py, it sets that directory for Stage dir and Output dir, but not for Perf. logging prefix. Using the perflogdir option instead in the reframe/settings.py has no effect.

Using the command line option --perflogdir seems to work fine.

@mand35 You are right this is a bug. Thanks for spotting!

How to reproduce:

1. Set logdir as a system attribute in the configuration file:

                'logdir': '/foo/logs',
   

2. Run reframe:

   ./bin/reframe -l
   

   ./reframe.py: stage and output refer to the same directory; if this is on purpose, please use also the `--keep-stage-files' option.
