Yes it was just a normal library - you could make syscalls elsewhere but they were neither documented or stable.

OpenBSD has been taking this model to a more modern design, where libc is blessed, and only it can make syscalls, by having a special attribute set. This is designed as a security measure, to stop arbitrary code using syscalls.
