Since the bump of assimp to 5.0.1, we have build failures on mips64el, due to relocations being truncated. The issue seems to be quite similar to the one on m68k coldfire, as both m68k and MIPS have this -mxgot gcc option to switch to using a GOT that has no size limit (but causes less efficient code to be produced). Here as well, the overall relevance of assimp on mips64(el) platforms being probably very limited, the incentive to search for a better solution is pretty limited.
