#     kbuild: move headers_check rule to usr/include/Makefile
#     
#     Currently, some sanity checks for uapi headers are done by
#     scripts/headers_check.pl, which is wired up to the 'headers_check'
#     target in the top Makefile.
#     
#     It is true compiling headers has better test coverage, but there
#     are still several headers excluded from the compile test. I like
#     to keep headers_check.pl for a while, but we can delete a lot of
#     code by moving the build rule to usr/include/Makefile.
