I do clang --target=arm-unknown-none-eabi compilation and lld linking with the toolchain (STL headers and libraries) from
without problems, but when I want to install the toolchain via apt-get
and run the build process I got following warnings
...

Can I ignore this warnings or is there any way to solve this (e.g., by installing an additional/missing library or a dedicated llvm-objdump options)?
Note: Compared to Ubuntu20.04 there is no libnewlib-nano-arm-none-eabi available for Ubuntu22.04
E: Unable to locate package libnewlib-nano-arm-none-eabi
Thanks for the help
