This warning is added in this patch, when vmcoreinfo is empty. Though
maybe I did some typo here, I don't like it showing '--vmcoreinfo'
instead of just 'vmcoreinfo', will check this also.

Sorry I don't have a aarch64 system, will check it on ppc64le.

It showing "gdb not initialised" is weird, that should depend on
GDB_INIT flag, and this patch shouldn't touch it. Will check.
