Hi Andrew,

Thanks for the reviews.

Isn't a test with a custom linker script, especially one that's placing
text sections going to be architecture specific?  I would have expected
this to be a gdb.arch/ test?

If this does work more widely then maybe a list of the targets it has
been confirmed to work on would be good.

You can push a `try` branch to sourceware into your username namespace,
e.g. I could push to 'aburgess/try-my-awesome-fix' and the sourceware CI
will spot this branch, run its tests, and email you the results.  The
key is the 'try-' part of the branch name.  Though thinking about it,
I'm not sure if it runs all tests, or just a subset, I guess you'd have
to "try" it and find out.

I would like to try this but I don't have gdb write permission. I know I
need to send an email to admin-requests. Would you be willing to approve
me having write after approval access please?

Thanks,
Craig
