Yes, I saw that.

In the distant past, I used to run the testsuite against resource
constrained linux machines often of a different architecture from the
host I was running the tests from.  These machines would run gdbserver
built for that architecture.

Now, I don't recall whether corefile support in the testsuite actually
worked for those targets, but it at least seems possible due to the
various invocations of remote_exec which are present (prior to your
patch).

Do you think you could restore those calls to remote_exec in your
patch?  Or do you know for a fact that they do not work?
