 9.51.5 WebAssembly Module Layout
 --------------------------------
 
 'as' will only produce ELF output, not a valid WebAssembly module.  It
 is possible to make 'as' produce output in a single ELF section which
 becomes a valid WebAssembly module, but a linker script to do so may be
 preferrable, as it doesn't require running the entire module through the
 assembler at once.
