Peter A. Bigot 60ca2333dc cmake: toolchain: generalize exclusion of CXX options
-Wold-style-definition is not a supported option for C++ builds.  To
prevent it being passed:
* the list of compiler flags to be excluded from C++ builds is moved
  to be toolchain-specific;
* -Wold-style-definition is added to that list for gcc and clang;
* -Wold-style-definition is moved from zephyr_compiler_options to
  zephyr_cc_option so the option checking code is executed for it.

Anas Nashif deb7ff524a cmake: no-address-of-packed-member is not supported in older compilers
Add a version check to allow building with older GCC versions that did
not support this option.

Fixes #16607

Anas Nashif e82a9e9a55 compiler: no warnings on address-of-packed-member
With gcc 9.1.x on fedora 30 we are getting new warnings that turn into
errors when running sanitycheck. Disable those while the issues are
being addressed.

Relates to #16587

Danny Oerndrup 025ffa2492 cmake: Toolchain abstraction: Abstraction of implicit-int error flag
Introducing the macro toolchain_cc_warning_error_implicit_int which,
abstracts the implicit_int error flag thus leaving it to the toolchain
to decide whether this flag is needed or not.

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.

Danny Oerndrup 8e5a95e4df cmake: Toolchain abstraction: Introduce macros for MISRA SANE flags
The macros are named toolchain_cc_warning_error_misra_sane and
toolchain_cc_cpp_warning_error_misra_sane

These macros provide toolchain specific flag(s) relating to the MISRA
SANE configuration option.
The macros will place the flag(s) in a variable provided by caller,
which can then add to zephyr compile options.

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.

This is placeholder for extended warning flags, likely to change between
toolchains.

This is placeholder for base warning flags, common to most toolchains.
