(1) The Ubuntu cross toolchain does not support compiling for pre-v7
targets -- it doesn't have a v4t-only libgcc, only a v7 one, so when
that is linked into your binary then it will not work on a v4t target.
You'll need to find a different cross compiler which does support
targeting v4T. (Maybe the debian or codesourcery ones??)

(2) QEMU doesn't support emulating the ARM920T.
