Grissiom 11026d0579 lpc43xx: clean the .o before building M0 and M4
SCons will omit the file in parent dir of SConstruct somehow and build
the object files in that dir instead of in variant dir. This cause
problem because we cannot mix the object files between M0 and M4 which
SCons failed to rebuild. So we have to manually remove the files before
building.
