To pass a linker flag, you need to to -Wl, and the linker flags you
want to pass you can get from the linker (ld) documentation. 

  $ gcc -o foo.exe -Wl,-Map,foo.map foo.c

will produce a foo.map file.

To dump the map to standard error, use --print-map or -M. You should also 
consider adding -Wl,--cref for cross-referencing.

  $ gcc -o foo.exe -Wl,-M foo.c 2>&1 | less
  $ gcc -o foo.exe -Wl,--print-map foo.c 2>&1 | less
