zero build failure on icedtea7 trunk

[Matthias Klose]

current icedtea7 fails to build, patches/shark.patch is missing. while trying to 
create a patch I noticed that the files in the build directory are hard linked 
to the ports directory. how is a patch supposed to work? fixing it directly 
works for me.
