when trying to use the hwtimer on the msb-430h I get this error during 

/home/milan/riot/RIOT/bin/cpu.a(hwtimer_cpu.o): In function 
/home/milan/riot/RIOT/cpu/msp430-common/hwtimer_cpu.c:74: undefined 
reference to `timerA_init'
collect2: ld gab 1 als Ende-Status zurück
make: *** [all] Fehler 1

void timerA_init(void) is defined in 
RIOT/cpu/msp430x16x/hwtimer_msp430.c, the build of the object was

-rw-r--r-- 1 milan milan 9600 Mai 15 10:15 ../../RIOT/bin/hwtimer.o

Is something missing like ar rcs $(RIOTBASE)/bin/hwtimer.a 
$(RIOTBASE)/bin/hwtimer*.o ?
But In Makefile.modules I found:

# exclude hwtimer, because it is part of the kernel but the define is 
needed for auto_init
export BASELIBS = $(shell echo $(BL)|sed 's/[^ ]*hwtimer.a//')

Full linker call is:

msp430-gcc /home/milan/riot/RIOT/bin/startup.o -o 
-Wl,--start-group  /home/milan/riot/RIOT/bin/posix.a 
/home/milan/riot/RIOT/bin/cc110x_spi.a /home/milan/riot/RIOT/bin/cpu.a 
/home/milan/riot/RIOT/bin/core.a /home/milan/riot/RIOT/bin/sys.a 
/home/milan/riot/projects/hello-world/bin/hello-world.a -lm 
-mmcu=msp430f1612 -lgcc /home/milan/riot/RIOT/bin/startup.o

Although I am using the hello-world project here, it uses the hwtimer 
(the hello-world project on github does not). However same error also 
appears at other projects which use the hwtimer.

used gcc version is:
msp430-gcc (GCC) 4.6.3 20120301 (mspgcc LTS 20120406 unpatched)

and used make version is:
GNU Make 3.81

RIOT is the current git version
