+Subject: [PATCH] libatomic: Do not enforce march on aarch64
+
+OE passes the right options via gcc compiler cmdline via TUNE_CCARGS
+this can conflict between -mcpu settings and -march setting here, since
+-mcpu will translate into an appropriate -march, lets depend on that
+instead of setting it explicitly
