Problems interrupting remote target on powerpc

[Chris Packham]

Hi GDB,

I've had a few users report to me issues with interrupting a running
process after continuing when attached to a remote gdbserver running
on a powerpc target. Everything seems to work properly on arm and
aarch64 so there might be some powerpc or big-endian specific issue
lurking.

The gdbserver version we're currently using is from gdb-11.2 built
from source and most users have gdb-multiarch 12.1 from ubuntu 22.04
(some might still be using gdb-multiarch 10.2 from a PPA).

Does this ring any bells for anyone? I'm going to try and get hold of
a powerpc target to test with to see if I can reproduce it for myself.

Thanks,
Chris
