3785289f97 tools/nolibc: include nolibc.h early from all header files 
Inclusion of any nolibc header file should also bring all other headers.
On the other hand it should also be possible to include any nolibc header
files
in any order.

Currently this is implemented by including the catch-all nolibc.h after the
headers own definitions.
This is problematic if one nolibc header depends on another one.
The first header has to include the other one before defining any symbols.
That in turn will include the rest of nolibc while the current header has
not defined anything yet. If any other part of nolibc depends on
definitions from the current header, errors are encountered.
This is already the case today. Effectively nolibc can only be included in
the order of nolibc.h.

Restructure the way "nolibc.h" is included.
Move it to the beginning of the header files and before the include guards.
Now any header will behave exactly like "nolibc.h" while the include
guards prevent any duplicate definitions.

a6a054c8ad tools/nolibc: add target to check header usability 
Each nolibc header should be valid for inclusion irrespective of any
special ordering requirements.

Add a new make target, based on the old kbuild "make header_check" target
to validate this requirement.

For now the check fails, but the following commits will fix the issues.

e5407c0820 tools/nolibc: use intmax definitions from compiler 
The printf format checking in the compiler uses the intmax types from

Instead use the types already provided by the compiler.

4c99fbc6a0 tools/nolibc: handle intmax_t/uintmax_t in printf 
In nolibc intmax_t and uintmax_t are always the same as
(unsigned) long long/uint64_t as 128bit numbers are not supported.
Even libcs that do support 128bit numbers often fix intmax_t to 64bit
as it is used in ABIs and any change would break those.

5f40eef1c7 selftests/nolibc: drop unnecessary sys/io.h include 
The include of sys/io.h is not necessary anymore since
commit 67eb617a8e ("selftests/nolibc: simplify call to ioperm").
It's existence is also problematic as the header does not exist on all
architectures.

0efdedb335 tools/include: make uapi/linux/types.h usable from assembly 
The "real" linux/types.h UAPI header gracefully degrades to a NOOP when
included from assembly code.

Mirror this behaviour in the tools/ variant.

Test for __ASSEMBLER__ over __ASSEMBLY__ as the former is provided by the
toolchain automatically.
