For arm, add -fno-tree-vrp to COPTS when compiling softfloat.c.

CVS commit: src/lib/libc/softfloat
Module Name:src Committed By: matt Date: Sun Aug 5 04:27:42 UTC 2012 Modified Files: src/lib/libc/softfloat: softfloat-for-gcc.h Log Message: ARM EABI (AAPCS) uses different names for the softfloat routines that the normal GCC ones. So after we redefine softfloat's to be what (old) GCC wants, we redefined the old GCC names to what ARM EABI want (but only if we are using ARM EABI). We do this for routines not compiled by softfloat so can just have these redefinitions in one place.
