From b216435bb362df10c45f544b78d8c884eaa901fd Mon Sep 17 00:00:00 2001
From: Khem Raj <raj.khem@gmail.com>
Date: Fri, 8 Jan 2016 07:01:02 +0000
Subject: [PATCH 21/32] Define _GNU_SOURCE for MREMAP_MAYMOVE definition
musl guards MREMAP_MAYMOVE with _GNU_SOURCE unlike glibc which uses
__USE_GNU
Fixes errors like
error: 'MREMAP_MAYMOVE' undeclared (first use in this function)
