Hello Nicolò,

This is definitely a bug that I encountered today. I'm convinced it's a
bug because I came across this page that says so:
https://newlib.sourceware.narkive.com/kfT8XDEe/building-libc-nano-and-libg-nano

The git repo it links to has the following shell function. I think we
should emulate its behavior.

(On a slightly unrelated note, can someone PLEASE accept my patch in bug
44750 for a different arm-none-eabi issue. It's desperately needed.)

copyNanoLibraries() {
	(
	source="${1}"
	destination="${2}"
	messageA "\"nano\" libraries copy"
	multilibs=$("${destination}/bin/${target}-gcc" -print-multi-lib)
	sourcePrefix="${source}/${target}/lib"
	destinationPrefix="${destination}/${target}/lib"
	for multilib in ${multilibs}; do
		multilib="${multilib%%;*}"
		sourceDirectory="${sourcePrefix}/${multilib}"
		destinationDirectory="${destinationPrefix}/${multilib}"
		mkdir -p "${destinationDirectory}"
		cp "${sourceDirectory}/libc.a" "${destinationDirectory}/libc_nano.a"
		cp "${sourceDirectory}/libg.a" "${destinationDirectory}/libg_nano.a"
		cp "${sourceDirectory}/librdimon.a" "${destinationDirectory}/librdimon_nano.a"
		cp "${sourceDirectory}/libstdc++.a" "${destinationDirectory}/libstdc++_nano.a"
		cp "${sourceDirectory}/libsupc++.a" "${destinationDirectory}/libsupc++_nano.a"
	done

	mkdir -p "${destination}/${target}/include/newlib-nano"
	cp "${source}/${target}/include/newlib.h" "${destination}/${target}/include/newlib-nano"

	if [ "${keepBuildFolders}" = "n" ]; then
		messageB "\"nano\" libraries remove install folder"
		maybeDelete "${top}/${buildNative}/${nanoLibraries}"
	fi
	)
}
