[PATCH] configure.ac: option for user-defined-trusted-dirs

[justinpopo6@gmail.com]

From: Justin Chen <justinpopo6@gmail.com>

User-defined-trusted-dirs is a variable used for adding additional
default library search dirs for the dynamic loader. Add the ability
to allow users to set it from the configure script.
