fix genenv when using svn based enviroment directory
Hi
When setting the default env of barebox to a svn directory the build stops
with questions on removal and the barebox env is polluted with svn files.
The patch below fixes that.
Tested with 2011.03.1. Newer versions don't boot anymore on my pcm043 :-(.
