Hello, riot developers.
Yesterday i have seen an update regarding RIOT support on stm32f4discovery
board.
I downloaded and tried to compile hello-world project for this board, but
got a bunch of errors. After fixing some path i am a bit stuck with
following errors:

> /home/mfa/sat/lib/gcc/arm-none-eabi/4.7.3/../../../../arm-none-eabi/lib/thumb/cortex-m4/libg.a(lib_a-sbrkr.o):
> In function `_sbrk_r':
> /home/mfa/Desktop/compiler/summon-arm-toolchain/build/arm-none-eabi/thumb/cortex-m4/newlib/libc/reent/../../../../../../../gcc-linaro-4.7-2013.01/newlib/libc/reent/sbrkr.c:58:
> undefined reference to `_sbrk'

May be there are something wrong with my toolchain, which one do you use to
build the project for stm32?
That`s the log i got with modifed makefiles:

And that`s log from raw sources from git(downloaded and no any modification
made with them):

Thanks!
Regards, Aleksander.
