require 2.6.27 for proper signalfd handling

<zzam> kay: ping I found out why udev-145 fails on some
            systems with kernel 2.6.25 and 2.6.26
<zzam> kay: it is because glibc was compiled against linux-headers-2.6.27
            or newer and issues signalfd4 syscall which was introduced in
            kernel 2.6.27 and not older signalfd syscall
