It seems that initcalls from the libc side of the house aren't being
called because they're not in the initcall section. The one that
matters here is init_syscall_regs in arch/um/os-Linux/skas/mem.c. If
you run with initcall_debug, you'll notice its absence. As to why,
and why it depends on -fno-unit-at-a-time, I have no idea.
