* wasm internal linker: use the main symbol (without WASM_SYM_EXPLICIT_NAME,

  i.e. not an alias) to define code section names in the wasm object reader.
  For example, the section for the INITHEAP function is now called:
    .text.n_SYSTEM_$$_INITHEAP
  instead of
    .text.n__FPC_InitHeap
  (which is based on an explicit alias for the function - '_FPC_InitHeap')
