Makefile for nrf51sdk - makefile

Question

I am working on programming a nrf51822 evaluation board(This one). I have been looking at this site to program it and have gotten the blinking program to work.
I want to modify the makefile provided on the site previously mentioned, such that when I go along I pretty much only have to add to the list of files to compile. Below is what I have been trying to get to work, but I am not very good with makefiles.
CC := /opt/arm-2012.09/bin/arm-none-eabi-gcc

NRF51_SRC := $(NRF51_SDK)/Nordic/nrf51822/Source

OBJDIR = .
OBJDIR += $(SRC)/templates/

CFLAGS = -mcpu=$(CPU)

./segger/segger.sh $(PWD)/burn.seg
clean:
rm *.o *.out *.hex *.seg *.map *.bin *.hex
When it runs make it just outputs the following:
/opt/arm-2012.09/bin/arm-none-eabi-gcc -L"/opt/arm-2012.09/arm-none-eabi/lib/armv6-m" -L"/opt/arm-2012.09/lib/gcc/arm-none-eabi/4.7.2/armv6-m" -Xlinker -Map=main.map -mcpu=cortex-m0 -mthumb -mabi=aapcs -T/opt/nrf51sdk/Nordic/nrf51822/Source/templates/gcc/gcc_linker_script_nrf51.ld main.o system_nrf51.o nrf_delay.o gcc_startup_nrf51.o -o main.out

arm-none-eabi-gcc: error: gcc_startup_nrf51.o: No such file or directory
make: *** [main.out] Error 1
Is there anyone around here that can help me with this?

This at least works for now :)
