When it strips files, the hardlink is broken and replaced with a
stripped copy.

Nothing does but the copy in image remains unstripped as above.

That is not really the way the sysroot has been intended to be used.
Inhibiting the sysroot stripping for target files would seem to be the
best thing to do if you do wish to use the sysroot that way:

INHIBIT_SYSROOT_STRIP_class-target = "1"
