CGO_ENABLED=0 GOOS=linux GOARCH=<b>amd64</b> ./make.bash is normal! Only the "arm" is not normal.

#/usr/local/go/src/cmd/ld/lib.c code:

vi cmd/ld/lib.c
661 switch(thechar){
662 case '8':
663 argv[argc++] = "-m32";
664 break;
665 case '6':
666 argv[argc++] = "-m64";
667 break;
668 }

I'm really not sure about anything in OSX, but perhaps the command should read

export CGO_ENABLED=0 ; export GOOS=linux ; export GOARCH=arm ; ./make.bash

instead?
