aa88e318f2 multilib_header_wrapper: Drop using __MHWORDSIZE
This is not needed as __WORDSIZE already represents same value and is
directly defined in wordsize.h, this simplifies the multlib headers

c131b23cdb multilib_header: Fall back to worsize form libc for bpf target
Setting bpf to use 64bit for wordlength is not right, it happens to
work perhaps becuase the targets its being run on are 64bit inherently

55b6734be9 multilib_header_wrapper.h: Remove pragma once
This was a bandaid to avoid include recursion caused by multilibbed
wordsize.h

ffae400179 meta/lib+scripts: Convert to SPDX license headers
This adds SPDX license headers in place of the wide assortment of things
currently in our script headers. We default to GPL-2.0-only except for the
oeqa code where it was clearly submitted and marked as MIT on the most part
or some scripts which had the "or later" GPL versioning.

The patch also drops other obsolete bits of file headers where they were
encoountered such as editor modelines, obsolete maintainer information or
the phrase "All rights reserved" which is now obsolete and not required in
copyright headers (in this case its actually confusing for licensing as all
rights were not reserved).

More work is needed for OE-Core but this takes care of the bulk of the scripts
and meta/lib directories.

The top level LICENSE files are tweaked to match the new structure and the
SPDX naming.

362aa431d8 multilib_header_wrapper.h: Use #pragma once
Avoid infinite include loops, especially with bits/wordsize.h which is
now possible with the synthesized headers since we now also synthesize
bits/wordsize.h itelf for some arches e.g. arm/aarch64

In cases where extra preprocessing tools are used such as clang-tidy
e.g. and these tools are not passed the knowledge about architecture
then case comes where we enter into header include loop for
bits/wordsize.h, since this template does explicitly include
bits/wordsize.h

To fix this emits the pragma once at beginning of file, this is better
solution than include guards, and pragma once is practically supported
on all compilers except few e.g. cray c/c++ compiler

c870856a2d multilib_header: recognize BPF as a target
When building with `clang -target bpf` using the
multilib_header, a recursion was unavoidable because
bits/wordsize.h would #include itself, still lacking
a definition for __MHWORDSIZE or __WORDSIZE.

8b41b5ddfe multilib_header: Update wrapper to handle arm 32/64 bit
Having arm 32/64 bit headers coexisting turns out to be tricky. Unfortunately
our wrapper works using wordsize.h and this differs on arm so we can't use it.

Therefore replicate the logic here for arm. I did look into writing our
own wordsize.h but we also need to remap kernel headers on arm and
since wordsize.h comes from libc, that doesn't work for kernel headers.

a447c3e859 multilib_header.bbclass: Add oe_multilib_header wrapper
This helper function and associated header will allow us to
resolve two/three header files that conflict due to contents
that change based on wordsize and ABI.
