Note, Glibc does not specialize its lookup code for those platforms; instead, they use user-visible type Elf_Symndx (exposed via link.h, also on musl) to denote the type of hash table entries; Alpha and s390 override this type appropriately in their arch-specific headers. This suggests that musl should also define Elf_Symndx as a 64-bit type (otherwise it's incompatible), and then dynlink.c admits a cleaner fix (i.e. using Elf_Symndx where appropriate, without a new #ifndef).
