No we don't need to support old binaries: 2.32 will be baseline > This matters because in the GLIBC_2.32 case, old binaries will not work > anyway, so we may as well require that they are rebuilt without > DT_INIT/DT_FINI. In this case, the glibc master defaults should work.

Per the review comments on ARC port last year [1], I was advised to remove the ARC specific crt*.S so those are anyhow gone.
