[pacman-dev] [PATCH 2/2] makepkg: Search/Add real library names libdepend link to

[Mohammad Alsaleh]

  Search library paths for libdepend. If found and its realpath is not
  of the name scheme "libdepend.ver". Add the real library name to
  depends.

  Coupled with code in the libprovides side, this is necessary as the
  real library name is the one binaries depend on. And it is the one we
  can obtain version/arch info from.

  Note: parsing library paths from `ldconfig -v` output is relatively
  slow.
