Wolfgang Grandegger 07b05f439a package/patchelf: add patch for rpath sanitization under a root directory
The patch allows to use patchelf to sanitize the rpath of the buildroot
libraries and binaries using the option "--make-rpath-relative <rootdir>".
Recent versions of patchelf will not built on old Debian and RHEL systems
due to C++11 constructs. Therefore we stick with v0.9 for the time being.

Subject: [PATCH] Extract a function for splitting a colon-separated string
We're going to need this logic in another place, so make a function of
this.
