It apparently breaks the much more common case of:
gdb program -ex 'b main'
You should just use:
gdb -q -ex "set gnutarget elf32-littlearm" -ex "file ./vmlinux"
as changing options required before the image load is generally an advanced
topic so I guess the "file" command requirement is OK in such case.
Thanks,
