It appears that this change was submitted despite Arthur's comment. This impact is that symlinks are created with absolute path names rather than relative path names. This isn't a big deal if the link is being created directly on the target system. 

It does impact anyone who attempts to build/install in a non-standard location and then installs the files in the correct location on the target system. This is often the case when cross compiling or when building packages as a non-root userid.

I would prefer to see fromfile used rather than fromname to keep the soft links relative.
