See https://sourceware.org/pipermail/libc-alpha/2020-November/119575.html lib{mach,hurd}user.so gets relocated before libc.so, but its references to strpcpy and memcpy would need an ifunc decision, which e.g. on x86 relies on cpu_features, but libc.so's _rtld_global_ro is not relocated yet. We can however just make lib{mach,hurd}user.so only call non-ifunc functions, which can be relocated before libc.so is relocated.
