I'm proposing to move `linux/tools/include/nolibc/nolibc.h` to the
UAPI interface.
It would then be included in `linux/types.h`
Would love feedback before I work on a patch.

I do not think nolibc.h is a good starting point.  The header is
pretty much incompatible with everything, including multiple
translation units that include it, so including it from
<linux/types.h> will not work.

Currently compiling the following program fails:

#include "linux/signal.h"
void main(void){}

Because of `./asm/signal.h:127:2: error: unknown type name ‘size_t’`.

I tried patching with `#include <stddef.h>` but there's a local file
with the same name overriding the include.

<stddef.h> is expected to be provided by the compiler. It's probably
easier to fix your build environment.
