GDB can be built with or without Python support. When built with Python
support this can cause a particular problem: The gdb executable relies
on shared libraries that are bound to a specific Python version. But
since most Linux distributions typically ship with a single version, it
is very difficult to choose which one to target when building GDB.
When GDB executes, if it fails to load the shared libraries it will exit
immediately with an error code of 127 and output resembling this:
/home/carles/bin/zephyr-sdk/arm-zephyr-eabi/bin/arm-zephyr-eabi-gdb:
error while loading shared libraries: libpython3.8.so.1.0: cannot open
shared object file: No such file or directory
There are two known approaches to shipping multiple gdb executables:
- The Zephyr SDK ships a default gdb with Python enabled, and then a
separate gdb-no-py executable with Python disabled
- GNU Arm Embedded ships with a default gdb with Python disabled, and an
additional gdb-py with Python enabled
To mitigate the problem of not being able to debug, fall back to a
'gdb-no-py' if it exists whenever the standard gdb executable fails to
even run.

Ensure > is an independent argument.
The ; will ensure that the `>` and `outfile` are given as two arguments
and thus ensure correct behavior in all cases.

This command add support for `<command>_flag_final` to all bintools
commands.
This allows users that has special use-cases to use a CMake script
for bintool command execution, and thereby have full control of command
invocation and argument processing.
Example of how to specify the property for such use:
Calling a custom script for elfconvert command:
set_property(TARGET bintools
PROPERTY elfconvert_command ${CMAKE_COMMAND})
set_property(TARGET bintools
PROPERTY elfconvert_flag "")
set_property(TARGET bintools
PROPERTY elfconvert_flag_final -P elfconvert.cmake)
set_property(TARGET bintools
PROPERTY elfconvert_flag_strip_all "-DSTRIP_ALL=True")
set_property(TARGET bintools
PROPERTY elfconvert_flag_infile "-DINFILE=")
set_property(TARGET bintools
PROPERTY elfconvert_flag_outfile "-DOUT_FILE=")

GNU/bintools abstraction completed.
The following commands and flags are now available in bintools:
- memusage
- elfconvert
- dissassembly
- readelf
- strip
The bintools template has now been updated with more description which
will be useful when adding support for more toolchains in future.

Added support for creating an assembly listing containing all sections
like rodata, data and debug sections, not just those expected to
contain instructions.

This abstracts the interface for generation of the strip command
line, by naming the desired actions instead of directly setting the
command parameters, which then opens up for other binary tool sets
which may require different arguments to achieve the desired result.
The intent here is to abstract Zephyr's dependence on toolchains,
thus allowing for easier porting to other, perhaps commercial,
toolchains and/or usecases.
No functional change expected.

The method for getting a memory usage report printed during build, is
based on a GNU linker (ld) option flag, and thus is not necessarily
supported by other toolchain binary tools.
The introduced cmake macro allows for a given toolchain to specify how
the memory usage report is to be generated, and whether the command for
generation, if any, is to be added to the post_build_commands and the
post_build_byproducts lists of the top level CMakeLists.txt

This forms the foundation for the abstraction of the binary tools,
where the following steps are taken:
- Move binary tool resolving, such as objcopy, objdump, readelf and
so forth, out of compiler definitions and place in a dedicated binary
tools folder with the binary tools supplier as subfolder, similar to
the compiler and linker directories.
- Create binary tool sets, gnu, host-gnu and llvm.
- Each toolchain selects the required set of binary tools by setting
BINTOOLS via its generic.cmake as it also does for compiler and linker.
