i'm not familiar with how stacking works and the syscalls.list, but the 64bit
arches need to do something different from the 32bit arches.  on 64bit,
prlimit64 is just an alias to prlimit.  for 32bit arches, they need to declare
the list themselves.

sysdeps/unix/sysv/linux/wordsize-64/syscalls.list lists it unconditionally
(for the alias), and from there, it seems that all the 32bit arches add it to
their arch-specific list.

sysdeps/unix/sysv/linux/sh/syscalls.list:prlimit64    EXTRA   prlimit64       i:iipp  prlimit64
sysdeps/unix/sysv/linux/powerpc/powerpc32/syscalls.list:prlimit64     EXTRA   prlimit64       i:iipp  prlimit64
sysdeps/unix/sysv/linux/i386/syscalls.list:prlimit64  EXTRA   prlimit64       i:iipp  prlimit64

ports/sysdeps/unix/sysv/linux/m68k/syscalls.list:prlimit64    EXTRA   prlimit64       i:iipp  prlimit64

hppa is the only one here i can see missing.  and probably the new
"generic/wordsize-32/" ...
