Fix a build failure by using __prlimit64 as the internal
function name for the versioned symbol prlimit64. Without
this patch the build system attempts to alias prlimit64
to itself and that is invalid.
All other arches have this in their syscall list. Looks like hppa
is missing it though and breaks one or two apps that try to call it.
