Currently, package raspi-copies-and-fills breaks stuff for ARMv7! Remove it, or udevd, getty and others won't work!
No, it does. You have broken compiler.
Currently, the same Raspbian is distributed for ARMv6 RaspberryPi 1 and ARMv7 RaspberryPi 2. This means that all packages are compiled –with-arch=armv6 –with-fpu=vfp. However, this also means, that gcc assembler does not support some NEON instructions even when –mfpu=neon is set (no idea why).
You need gcc compiled with –with-arch=armv7-a –with-fpu=vfpv3-d16. For example from stock armhf Debian.
I have edited /etc/apt/sources.list so now it reads:
deb http://merlin.fit.vutbr.cz/debian/ jessie main contrib non-free deb-src http://merlin.fit.vutbr.cz/debian/ jessie main deb http://security.debian.org/ jessie/updates main deb http://merlin.fit.vutbr.cz/debian/ jessie-updates main
(of course pick a mirror that is in your network)
Maybe you should also change /etc/apt/sources.list.d/raspi.list to get Jessie.
apt-get update, apt-get install debian-archive-keyring, apt-get update
apt-get dist-upgrade, apt-get install gcc-4.9 gcc-4.9-base libgcc-4.9-dev libgcc1 gcc
(oh and dpkg -l | grep gcc and remove old gccs)
Continue with Installing GnuRadio from source on Debian Jessie.
