This error message isn't related to the QEMU code for defining
the tricore board -- it's complaining that your ELF file has
two program headers which define overlapping bits of code to
be loaded.
What does tricore-objdump --all-headers Test.elf say?
(I don't know the exact name of the objdump binary for your
cross toolchain, so it might be slightly different.)
