This shows nicely formatted error messages for missing symbol names and for out-of-flash, out-of-RAM conditions (on microcontrollers with limited flash/RAM). Unfortunately the missing symbol name errors aren't available on Windows and WebAssembly because the linker doesn't report source locations yet. This is something that I could perhaps improve in LLD.
