#     powerpc/64s: Always disable branch profiling for prom_init.o
#     
#     Otherwise the build fails because prom_init is calling symbols it's
#     not allowed to, eg:
#     
#       Error: External symbol 'ftrace_likely_update' referenced from prom_init.c
#       make[3]: *** [arch/powerpc/kernel/Makefile:197: arch/powerpc/kernel/prom_init_check] Error 1
