Only compile-tested, admittedly.

You're right. But I'm afraid I'll need more specific advice to fix
that. Doing

-sysinfo                EXTRA   sysinfo         i:p     sysinfo
+sysinfo                EXTRA   sysinfo         i:p     __sysinfo       sysinfo

to syscalls.list wasn't enough. Where should I put a prototype for
__sysinfo? I assume sysdeps/unix/sysv/linux/sys/sysinfo.h is the wrong
place, since that's the installed header.
