[committed, PATCH] Add --[no-]map-whole-files for gold compatibility

[H.J. Lu]

Gold supports:

  --map-whole-files           Map whole files to memory (default on 64-bit hosts)
  --no-map-whole-files        Map relevant file parts to memory (default on 32-bit hosts)

This patch adds --[no-]map-whole-files command line options for gold
compatibility.  They are ignored for ld.  I checked it in.
