First though I would also suggest that you verify that the software you are trying to build has a hope of compiling under ARM else you might end up spending a lot of time on something which will be very difficult to achieve. It is not at all uncommon for source code to need significant porting to run on different architectures (i.e., ARM vs. x86) and it not to have been done. A cursory glance at the project indicates to me that it probably does not, or at least not fully.
What makes you think that? ARM isn't all that different from x86, and I've put some effort into ensuring it's portable even to big-endian architectures like MIPS.
I noticed nothing in a scan of the README (though I was looking for 'arm' and not 'mips' which was a mistake since I've not done this kinds of stuff in a while) and noticed no assembly for anything but x86's. But it is not unheard of for people to optimize for an architecture with assembly while supporting other architectures with compiled code. And also common to build a sub-set of functionality on less well supported architectures. That's why I said 'or at least not fully.'
But, since you are here, is it known that the code should work on his platform, or is he blazing trails in trying to get it going?
