musl and RTLD_DEEPBIND

[Fabian-Gruenbichler]

libc defines RTLD_DEEPBIND for two musl target envs:

src/unix/linux_like/linux/musl/b64/s390x.rs:pub const RTLD_DEEPBIND: c_int = 0x8;
src/unix/linux_like/linux/musl/b32/riscv32/mod.rs:pub const RTLD_DEEPBIND: c_int = 0x8;

I can't find a definition of that constant in musl's sources, so I suspect it might have been wrongly copied over from somewhere that does have it (like glibc).

since I don't really have a clue about musl, I'll leave the rest to you ;)

this was prompted by rust-lang/rust#135591
