+Subject: [PATCH] confiure.ac: Believe the cflags from environment
+
+In some toolchains e.g. OpenEmbedded -march options
+are passed on compiler cmdline, it does not use
+the expected target triplets to make these decision
+during configure.
+
+Secondly, dont set armv4 for march when no selection
+is made, since it is passed from cmdline
