Let me check the LoTR wiki:

-

It is not known if they are cross-breeds or a random occurrence in nature. They are supposed to be hardy warriors and great swordsmen. They are loyal to Sauron like many of the other people at Harad including the Haradrim. While it is doubtful that there is true trollish blood in these warriors, their sheer size and strength lends credence to the name by which they are known in other lands. At the end of the War of the Ring, the men of Far Harad were granted the region of Far Harad to maintain and keep for themselves. The Half-trolls were not included in this gift, and probably did not benefit from it.

So I guess the question is still unanswered. Based on what I read in the wiki, however, I think that the Half-Trolls were just big, strong Men of Far Harad. They were considered to be related to the Trolls by some because of their sheer size and brutality.
