Stop generating listings files during the build

As part of migrating away from the GNU binutils tools, we need to switch
to the LLVM version of tools such as objdump. However, 32-bit ARM
llvm-objdump does not generate correct disassembly for our mixed thumb
and ARM code binaries. Rather than generate incorrect listings files, we
are just removing these files from the build.
