Subject: [PATCH 4/7] base/stagebase.py: Seperate out the writing of the
 make.conf file
To: [hidden email]

By separating out the writing of the make.conf file, it keeps all code
to do so in one place. I also fixed the code to correctly set the
target chroot directories for PORTDIR, DISTDIR, PKGDIR and
PORTDIR_OVERLAY. The same code also re-writes make.conf toggling any
PORTDIR_OVERLAY setting during the clean() run.

Add target_distdir and target_pkgdir settings to defaults and catalyst.conf.
This allows for more flexibility between host and target settings.  They can be individually
configured this way.

Update target an source mounts from the configured settings.
