code_size_compare.py: run make clean before build libraries

Browse Source 
If we don't remove all executable files in current working
directory, we might measure code size between different architecture
and configuration. This generates a wrong code size comparison
report. This commit guarantees it runs `make clean` before build
libraries for code size comparison.
