Looking, I see:
# man -K "libc, -l" | more

. . .
But:
# man -K "libsys, -l" | more
#
(So nothing references libsys in a similar way.)
# readelf -drs /lib/libsys.so.7 | sort -k8,8 | grep "\<_*errno\>"

NAME
intro, errno – introduction to system calls and their error numbers
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <sys/syscall.h>
#include <errno.h>
. . .
(So "libc, -lc" is still referenced for errno in the man page.)
(errno is just used as an example above.)
