As far as I can tell the error is because the target and the host
disagree as to how many registers there are on the target,
While I have seen it only on i386<->x86_64 it should be the same problem:
http://sourceware.org/gdb/wiki/FAQ#line-53
15. When connecting to gdbserver I get Remote register badly formatted, g packet
     reply to long etc.
Your gdb 32bit/64bit architecture setting may not match that of gdbserver. Try
to load the executable by file first. You may also check set/show architecture.

Thanks, I had seen that also. I am already passing in the unstripped executable when I call gdb so I think it should have been set already. I try showing the architecture but it just reports arm which is not specific enough to give me a clue what is wrong, I assume it is some mismatch in expected floating point registers.
