gmp: Fix wrong detection of -march flag
Configure detects -march flag based upon target triplet, it wrongly passes -march=armv4 for all arm, this is unearthed when compiling with clang since it errors out with flags like /tmp/kraj01/a-0c2038.s:27: Error: selected processor does not support `bx r0' in ARM mode since it does not pass --fix-v4bx along with -march=armv4, which does not happen with gcc toolchain since this flag is passed impicitly hence this error was indetected Fixed thusly Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Ross Burton <ross.burton@intel.com>

+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
