The upstream build system uses symlinks to perform the build in the linux/
directory: this causes make to always fail the very first time it is called,
because apparentely it can't satisfy a dependency with a file created
during the same run.

This patch removes the symlink creation, since we make a copy of the needed
files in debian/rules.
