From 76a4f71e89722fd579daa559a1d24b3d710dbed6 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Fri, 8 Dec 2017 20:16:27 +0100 Subject: buildgcc: Add patch to work around Musl libc issue GCC includes `sched.h` after poisoning calloc(). This results in a build failure with Musl libc. We work around the issue by including `sched.h` earlier and throw around some void pointers so we only have to do it in one place.
