+It will add -mips64r6 and -mips64r2 to cmdline which will
+cause conflicts
+
+in OE we user mips32r2 and mips64r2 for mips arch versions
+so there is no benefit of detecting it automatically by
+poking at tools especially in cross env
+
+Fixes errors like
+
+linking -mnan=2008 module with previous -mnan=legacy modules
+failed to merge target specific data of file
