hurd: break relocation loop between libc.so and lib{mach,hurd}user.so
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.
