qimageblitz fails to cross build from source, because it compiles its
assembly file with the build architecture compiler and then fails
linking it. It uses plain gcc instead of the proper cmake variable
${CMAKE_C_COMPILER} there. It also determines whether to use certain
processor features (e.g. MMX) by looking at the architecture one is
building on (build architecture) instead of the architecture one is
building for (host architecture). The attached patch fixes both problems
and makes qimageblitz cross build just fine. Please consider applying
it.
