common.h dependence leak

[Kevin Huanpeng Du]

Hi, all:
I am study barebox, I want to remove all files not used, so I write this script.
here is a part of removing header (.h) files.
firstly, I didnot add LINE22 for speed.
but it not works for common.h.
I guess the file 'include/common.h' is leak of dependence in Makefiles.
Is anyone can check.
