[PATCH] ld-wrapper: Add '-rpath' flag for libraries passed by file name not ending in .so.

[Andreas Enge <andreas@enge.fr>]

Hello,

the attached patch should help to add an rpath for libraries passed by
an absolute file name on the command line, and that need not end in ".so",
but in ".so." followed by some version.

As it entails a full rebuild, I did not even test it yet and wait for
comments first.

Andreas


* gnu/packages/ld-wrapper.scm (library-files-linked): Include not only
  names of libraries ending in ".so", but also libraries ending in ".so.",
  followed by the version.
