How to dump objcopy output to stdout on macOS?

[Peng Yu]

The following command does not work on macOS.

$ /usr/local/opt/binutils/bin/objcopy -O binary --only-section=.text
1.o /dev/stdout
/usr/local/opt/binutils/bin/objcopy: /dev/stdout: Bad file descriptor
$ /usr/local/opt/binutils/bin/objcopy --version
