Subject: [PATCH] libavutil/error: fix build with musl toolchain
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add the feature test macro which is required for building with the
musl toolchain.

The feature test macro _XOPEN_SOURCE = 600 provides the XSI-compliant
version of strerror_r().
