From c8b9f095f0c1cbb2e5fecdfb31cdb39002e44f24 Mon Sep 17 00:00:00 2001 From: Sergio Prado Date: Wed, 2 Dec 2015 13:07:59 -0200 Subject: libtirpc: using sys/queue.h from staging Now that musl toolchains depend on netbsd-queue package, a implementation of sys/queue.h will always be available in the staging directory, so we can remove the patch that adds a local sys/queue.h implementation.
