gdb uses ptrace for accessing the x86 debug register?!. like in i386_linux_dr_set(). Can I use ptrace for a PPC architecture? There is no member u_debugreg in the struct user in sys/user.h Is there something missing in my cross-compiler, or is there no way to use ptrace?

For watchpoints? From memory the PPC Linux kernel lacks that interface.
