But there is with uClibc. (The syscall was introduced 5 years ago, you
can't expect uClibc to have adapted so quickly.)

I think I'd rather just put a patch for uClibc in aboriginal. Long-term,
I plan to A) migrate  aboriginal to musl, B) add nommu support to musl
(at least sh2).

So if it doesn't work with the last-ever uClibc release from 2012, I'm
ok with that. (You can always switch nsenter and unshare off in
menuconfig. It's not worth a compile-time probe for a dead project.)
