Because it's not part of the ABI?

There may be multiple ABIs, with multiple syscall ranges.
Userspace only needs to know if a syscall is available, not what the
valid syscall number range is.
The kernel does need to know the size of the full syscall table.

This invites the question as to why the __NR_syscalls macro is not
defined in uapi/asm/unistd.h on those architectures, where it will be
easier to spot? After all, asm/unistd.h includes uapi/asm/unistd.h
