RFR: 8301129: Link to debuginfo files should only be made after stripping

[Julian Waters]

Links to debuginfo files should only be made after strip is run, as doing so before can cause strip to wreck the embedded link and make the executable entirely un-executable in certain strange cases. It's safer to always just make the link after strip is called regardless
