They have some differences which makes impossible to write into the same source file:

They have different memory spaces. For example, if you tried to call printf from ARM9, it will crash.
They have different instructions. The difference is a little, but it can be a fatal problem.

How to fix it:

Write ARM9 code in another file, and compile with "-march=armv5te -mcpu=arm946e-s" instead of "-march=armv6k -mtune=mpcore."
Use a linker script for ARM9
Use objcopy to make ARM9 object file to load.

arm-none-eabi-objcopy -S -O binary arm9.elf arm9.bin
arm-none-eabi-objcopy -I binary -O elf32-little arm9.bin arm9.o
