Add __visible to generated code in compile_time_request.c so that the
main code can be compiled with -fwhole-program.

Detect avr gcc v4.8.1 and then disable warnings during the klipper.o
linking to suppress bogus "misspelled signal handler" warnings.

Add a DECL_CONSTANT macro to allow the firmware to define constants
that are to be exported to the host during the "identify" phase. This
replaces the existing hardcoded mechanism of scanning the Kconfig
header file for certain constants.

On GCC v6 the -fwhole-program option does not take effect when
-fuse-linker-plugin is also in effect. The -fuse-linker-plugin option
does not optimize as well as -fwhole-program, so explicitly disable
the linker plugin via -fno-use-linker-plugin.

Not including the out/*.d build files can cause the build to be
incomplete. In particular, without this fix, if the code is built for
ARM and then configured for AVR, the build can produce a corrupt AVR
binary.

Generate the data dictionary in out/klipper.dict on each build. This
makes it easier to use the dictionary when debugging.

Commit da305e6b changed the objcopy command to use the --dump-section
flag. However, the 2.24 version of avr-objcopy (which is common on
raspbian installs) does not support this flag. Avoid using
--dump-section and continue to use the -j option instead.

Default to O2 and set Os in the AVR makefile. Platforms besides AVR
are likely to produce better code with O2 so make that the default.

Some boards may not support the ADC hardware. Update the build so
that those commands do not need to be compiled if they are not
available.

Instead of creating a misc.h file in each board directory, create a
generic board directory and declare misc.h there.
