+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@gmail.com>

Looks good, but have you tried that the same patch does apply to all 4
versions we currently have?

Does chromium need a similar patch?

armv7 but v8 seems to integrate the fix (no idea since when).
