#     kbuild: do not pass $(KBUILD_CFLAGS) to scripts/mkcompile_h
#     
#     scripts/mkcompile_h uses $(CC) only for getting the version string.
#     
#     I suspected there was a specific reason why the additional flags were
#     needed, and dug the commit history. This code dates back to at least
#     2002 [1], but I could not get any more clue.
#     
#     Just get rid of it.
