bba15e0a0b examples/natmod: Use LINK_RUNTIME=1 when building for armv6m.
To get division helper functions, eg `__aeabi_uidiv`, `__aeabi_idiv` and
`__aeabi_uidivmod`.

887125fc58 examples/natmod/deflate: Fix build for Xtensa.
This commit provides the appropriate external symbol addresses to let
the "deflate" example natmod build for the Xtensa platform.

Unlike other natmods that require an external symbol list to build
without bringing in the whole runtime libraries set, this natmod is
referencing the `__modsi3` symbol which was removed from the ESP8266's
SDK but not present in ROM.  The latter only has a `__umodsi3`
implementation that only operates on unsigned values, and thus unable to
handle this natmod.  Thus, the extended library resolution process is
enabled for this natmod as a `__modsi3` implementation is made available
that way (still using ROM symbols whenever possible).  This also means
that symbols that appear in both ROM and external libraries sort of
co-exist in the final MPY file, with ROM symbols being used by natmod
code but the implementation from the library still exists in the final
MPY file, unused.

6760e00817 tools/mpy_ld.py: Add native modules support for RV32 code.
This commit adds support for RV32IMC native modules, as in embedding native
code into a self-contained MPY module and and make its exported functions
available to the MicroPython environment.

decf8e6a8b all: Remove the "STATIC" macro and just use "static" instead.
The STATIC macro was introduced a very long time ago in commit
d5df6cd44a.  The original reason for this was
to have the option to define it to nothing so that all static functions
become global functions and therefore visible to certain debug tools, so
one could do function size comparison and other things.

This STATIC feature is rarely (if ever) used.  And with the use of LTO and
heavy inline optimisation, analysing the size of individual functions when
they are not static is not a good representation of the size of code when
fully optimised.

So the macro does not have much use and it's simpler to just remove it.
Then you know exactly what it's doing.  For example, newcomers don't have
to learn what the STATIC macro is and why it exists.  Reading the code is
also less "loud" with a lowercase static.

One other minor point in favour of removing it, is that it stops bugs with
`STATIC inline`, which should always be `static inline`.

Methodology for this commit was:

1) git ls-files | egrep '\.[ch]$' | \
   xargs sed -Ei "s/(^| )STATIC($| )/\1static\2/"

2) Do some manual cleanup in the diff by searching for the word STATIC in
   comments and changing those back.

3) "git-grep STATIC docs/", manually fixed those cases.

4) "rg -t python STATIC", manually fixed codegen lines that used STATIC.
