I found a solution, when build .S file using multi-lib gcc, -mfloat-api=soft is not enough, option -Wa,-mfpu=softvfp also needs to be added to the command line to make AS generate .o file without tagging Tag_FP_arch.
Is it possible to make gcc pass -mfpu=softvfp to AS when building .S file with option -mfloat-api=soft by default ?
