Packagers often disable rpaths wherever possible. They can cause
confusion and, used carelessly, even security issues, and in the vast
majority of cases they're wholly unneccessary. notmuch's usage of rpaths
is rather innocuous, but I would still prefer to disable them when
they're not strictly needed.

Now, notmuch's configure script already tries to detect whether $libdir
is path of the standard library search path and disables -rpath in this
case. However, this detection logic invokes /sbin/ldconfig, which may
not be present on musl-based systems or at least not work as the
configure script expects. On my host, configure thus arrives at the
conclusion it needs to use -rpath even though $libdir is set to

Since it seemed easy and straightforward to just add an option to
explicitly disable rpaths, and I wanted to avoid adding musl-specific
code to the autodetection logic, I decided to go this route.
