+From 8fbb4e6797ed67310b74cbaaa061269db45a5b71 Mon Sep 17 00:00:00 2001
+From: Natanael Copa <ncopa@alpinelinux.org>
+Date: Tue, 29 Apr 2014 15:51:31 +0200
+Subject: [PATCH] linux-user/signal.c: define __SIGRTMIN/MAX for non-GNU
+ platforms
+
+The __SIGRTMIN and __SIGRTMAX are glibc internals and are not available
+on all platforms, so we define those if they are missing.
+
+This is needed for musl libc.
