Welp, I'm VERY close at this point thanks to some helpful information on the ODROID forums (I am building using a Pi2 and an ODROID C1). At this point, I'm stumbling on Chromium, which the current set up seems to be setting it for a Linux desktop build running gyp_run.pro. The problem is that this causes the following error:gyp name 'target_arch' is not defined while evaluating condition 'use_qt==1 and target_arch=="ia32"' in /home/flame/builds/qt5/qtwebengine/src/3rdparty/chromium/base/base.gyp
I'm still trying to solve the KHR issue on the Pi (despite already updating the header), but for now, the chromium situation is what has me in a gridlock. I can override the desktop build and instead recommend a cross compile in reference to itself, but I'm unsure as to how well this will go.
I am making documentation of what is going on so far so that I can relay an easier to follow guide for people who also are trying ot compile natively for the Pi.
