Merge pull request #25 from llunak/master

fixes for opensuse
suse: Backports from OBS and create symlinks in /opt/icecream/bin on openSUSE <= 12.2.
Fix icecc-create-env for relative paths

Sometimes the path where gcc finds liblto_plugin.so or specs file
is relative to its path. Therefore when gcc is added to the tarball
file in /usr/bin it looses the path to liblto_plugin.so or specs file.

Usually this bugs occurs to cross-compilling environments.

be more careful when cleaning up envs directory

I'm not sure if this could be actually (ab)used, but the original code,
if it failed to remove a symlink to a directory for some reason, could then
descend into this directory and start removing stuff there.
cleanup envs dir still with root privileges

Otherwise upgrade from older versions which kept some files
there owned by root:root may not work :(.

Revert "cleanup envs dir still with root privileges"

This reverts commit 2eed54af1c000968f164e68a59c5219002278c96.
Only quite old icecream versions caused this, and it feels somewhat less
hackish to just clean up in specfile.
cleanup envs dir in %post in specfile

A different way of handling 2eed54af1c000968f164e68a59c5219002278c96 .
