+Subject: [PATCH] Link with libatomic to enable C11 atomics support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Some architectures (mips) require libatomic to support proper
+atomic operations. Check first if support is available without
+linking, otherwise use the library.
