Subject: [bug#33820] [PATCH 8/9] gnu: kpackage: Transfer patches from NixOS.

From: Hartmut Goebel <[email-masked]>
Date: Fri, 21 Dec 2018 11:10:51 +0100

Transfer the NixOS patches for kpackage as of 2018-02-17:
- Allow external paths.
- Make QDirIterator follow symlinks.

Decided to use a patch for one of the "allow external paths" changes since
'substitute*' seems not to be robust enough.

* gnu/packages/patches/kpackage-allow-external-paths.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/kde-frameworks.scm(kpackage)[source]: Use it. <patch>: New
  phase.
