ATfE is fined-tuned with a particular focus on performance for newer
ARM products (post 2024) like 64-bit Arm Architectures (AArch64),
or the M-Profile Vector Extension (MVE, a 32-bit Armv8.1-M extension).

Because LLVM is widely compatible with GNU tools, When builiding with any
LLVM toolchain, you have to specify some settings to let the compiler
know what tools to use:

Linker:
Set :envvar:`CONFIG_LLVM_USE_LLD=y` to use LLVM linker.
set :envvar:`CONFIG_LLVM_USE_LD=y` to use the GNU LD linker.
#. Runtime library:
Runtime library:
Set :envvar:`CONFIG_COMPILER_RT_RTLIB=y` to use LLVM runtime library.
Set :envvar:`CONFIG_LIBGCC_RTLIB=y` to use LibGCC runtime library.
