[PATCH] kbuild: permanently fix kernel configuration include mess
Include autoconf.h into every kernel compilation via the gcc command line
using -imacros. This ensures that we have the kernel configuration
included from the start, rather than relying on each file having #include
<linux/config.h> as appropriate. History has shown that this is something
which is difficult to get right.
Since we now include the kernel configuration automatically, make
configcheck becomes meaningless, so remove it.
