Well, Autoconf has never handled this automatically for anyone else. :)
I don't do any specific checks for libnsl currently, yet it gets linked
automatically when build the program on Linux, at least.
Linux does shared library dependencies properly, so libraries can declare
dependencies on other shared libraries themselves if linked properly.
Unfortunately, not all platforms are as kind.
To make things more clear, automatic features in Linux may mask
problems which become real problems on other systems, or which crop up
if an optional library is not installed. For example, if you
application needs networking, and an existing optional library also
needs networking, then that existing library may draw in the libraries
that your application also needs. If that optional library is not
present, then your application may fail to link.
Unfortunately, there is no substitute for testing on a variety of
platforms.
