Baruch I use this one:
arm-2009q1-203-arm-none-linux-gnueabi-i686-pc-linux-gnu

Is the toolchain tied to kernel headers that was compiled against?

Yes. Apparently the 2009q1 toolchain is based on kernel version 2.6.30 which 
should be fine, but for some reason it does not have SFD_NONBLOCK and 
SFD_CLOEXEC in its sys/signalfd.h header file. 2010q1 (2.6.36 based) does have 
these defines. Both toolchains are quite old anyway.

Any help is appreciated,

I'm on archilinux using Sourcery CodeBench toolchain..

The signalfd(2) man page says that these flags (SFD_NONBLOCK and
SFD_CLOEXEC)
are only defined since kernel version 2.6.27. It seems that your toolchain
uses an older kernel. Which version of the Sourcery CodeBench do you use?
