Subject: [opkg-utils PATCH] update-alternatives: Fix link relocation support

Commit fcb26339000021eb9bb711aa264247aebcfdd4ae which added Debian-style
support for link relocation tries to relocate symbolic link on host OS,
resulting in following-like error when two alternative packages have
symbolic link source located in different directories (/bin/rev ->
/bin/busybox.nosuid and /usr/bin/rev -> /usr/bin/rev.util-linux):

  update-alternatives: renaming rev link from /bin/rev to /usr/bin/rev
  mv: cannot stat '/bin/rev': No such file or directory

Fix the issue by prefixing 'olink' and 'link' variable references with
path to targeted root filesystem's root directory.

Upstream-Status: Submitted [opkg-utils]
