+Subject: [PATCH] Fix hardfloat detection
+
+based on the same patch for nodejs which says :
+
+gcc has a builtin define to denote hard abi when in use, e.g. when
+using -mfloat-abi=hard it will define __ARM_PCS_VFP to 1 and therefore
+we should check that to determine which calling convention is in use
+and not __VFP_FP__ which merely indicates presence of VFP unit
+
+The fix has been provided by Khem Raj <raj.khem at gmail.com>
