Gdb will not read the main file from foreign architecture

I am trying to read the main ARM file on my Linux desktop, but it doesn't seem to be able to identify my main file. Is there a way I can tell gdb what type of my main file is?

$ file ~/daemon
./daemon: ELF 32-bit LSB executable, ARM, version 1, dynamically linked (uses shared libs), for GNU/Linux 2.0.0, not stripped
$ file ~/core
./core: ELF 32-bit LSB core file ARM, version 1 (SYSV), SVR4-style, from './daemon -v -v -v -v -e 10 -t foo'
$ gdb-multiarch ~/daemon ~/core

The generation platform is armv4, which gdb-multiarch has announced support for under the "set architecture" list.

EDIT: For clarification, my gdb desktop machine is "x86_64-linux-gnu", namely the 64-bit version of Intel Ubuntu.

This can help:

$ gdb-multiarch

The following only matters if your desktop (where you are trying to run gdb-multiarch) is x86.
