Add --[no-]map-whole-files for gold compatibility
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. * lexsup.c (ld_options): Add --[no-]map-whole-files for gold option compatibility.
