This isn't specific to crash; it's the result of a change in the
Linux/glibc ABI.  Specifically, the new ABI has a .hash.gnu section
whereas the old one has .hash.  Your linker option above causes both
sections to be included, so that the old dynamic loader can load a
binary built with a new toolchain.
