[libc-commits] [libc] [libc] Add a couple of constants to elf.h. (PR #216784)

[Alexey Samsonov via libc-commits]

https://github.com/vonosmas created https://github.com/llvm/llvm-project/pull/216784

* STT_GNU_IFUNC is a GNU-specific ELF symbol type used to implement ifunc's, which is often used in parser code.
* Add EM_PPC64 denoting 64-bit PowerPC architecture (in addition to i386/x86, ARM, and RISC types we already support).
