These are in the libgcc library.

These are syscalls, which need to be provided by you. There are stubs you can use in libgloss.
Only this example working well only without %d ? It?s insignificant for me sprintf (buff, "%s", "my_test");
If you compile with optimization, gcc will convert this to a string copy which needs no library calls.
powerpc-eabi-ld -Map ADLAP.map -o ADLAP.elf appl.o main.o hardware.o init.o -T lnk_mpc555_rom.lcf -L c:/555/libumas -lumas -lm -lc
Using ld to link is almost always a mistake. You should use gcc to link instead, and this will solve half your trouble, which is the failure to link in libgcc. If you really need to use ld directly, then use gcc -v to see what the correct linker command is, and then modify as necessary.
The other half is probably a bug in your linker script, not including the necessary libgloss system call stubs which will work on the simulator. If you are running on a bare board, then you will need syscall stubs that call monitor routines. Some of these may not be supported on the board, in which case you can return an error, and just avoid calling them.
