From my main workloop, I want to terminate the thread on certain conditions. There is an explanation on how to do so in IMX:Kernel Programming.

thread_terminate(getact_thread(thread_t thread)); I think "thread_terminate (current_act());" is the recommended method. It's what I use. Only problem: I can't seem to find the function getact_thread(). Any clues? How do I get rid of the thread? Do not, repeat DO NOT kill a thread from another thread. It is only safe to kill a thread from within itself. The most common way to get around this limitation is to check a flag in the thread that needs to exit and if the flag is true then exit the thread. So in your case, in your main thread you would set the flag, then signal your other thread using a semaphore. If you need to wait for the thread to exit, block on a semaphore in the main thread that the exiting thread signals just before terminating.
