[Xenomai] [PATCH] prepare-kernel: Only purge links from target directories

[Jan Kiszka <jan.kiszka@siemens.com>]

Only remove files from the target directory of patch_link if they are
missing in Xenomai AND are actually symbolic links. This is required
when merging Xenomai directories into non-empty kernel dirs.

This is not required for the current patch workload but helps us in 2.6
with integrating ftrace (we patch into include/trace/events there).
Would reduce our queue length by one if this could be merged
nevertheless.
