The canonical way to select or deselect an object during compilation
is to use this pattern in the relevant Makefile:
bar-$(CONFIG_FOO) := foo.o
bittiming.c instead uses some #ifdef CONFIG_CAN_CALC_BITTIMG.
Create a new file named calc_bittiming.c with all the functions which
are conditionally compiled with CONFIG_CAN_CALC_BITTIMG and modify the
Makefile according to above pattern.
