Similar to issue #7899.

Apply this diff (to compensate for issue #7936):

Then, this

# go install cmd/objdump && go build -o objdump.exe && start=$(go tool
nm objdump.exe | awk '/main.main/{print $1}') && end=$(echo $start | sed
's/.$/f/') && echo $start $end && go tool objdump objdump.exe $start $end

works, while that
 
# go install cmd/objdump && GOOS=windows go build -o objdump.exe &&
start=$(go tool nm objdump.exe | awk '/main.main/{print $1}') && end=$(echo
$start | sed 's/.$/f/') && echo $start $end && go tool objdump
objdump.exe $start $end

does not.
