Subject: [PATCH] gnu: prrte: Fix compilation.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The upgrade in 710d1984576a023878323e91b56f5c62b4a76271 turned out to be
broken.

* gnu/packages/parallel.scm (prrte)[arguments]: Remove now unnecessary
configure flags.  Add ‘adjust-pcc-link’ phase.
[native-inputs]: Add ‘pkg-config’.
[inputs]: Add ‘libnl’.
[outputs]: New field.
