Well, I have been pushing for those xcompilers 10 years ago, depending
on the distro you use, it is still not in Debian stable:

https://packages.debian.org/search?keywords=gcc-arm-linux-gnueabihf

So if you use Ubuntu, it is there since 12.04LTS:

http://packages.ubuntu.com/search?keywords=gcc-arm-linux-gnueabihf

Otherwise, if you want to avoid the "compile on the target", you could
also run the following qemu+docker trick, even though docker should
not be a requirement, it should be doable with chroot:

docker run -it --rm -v
/usr/bin/qemu-arm-static:/usr/bin/qemu-arm-static philipz/rpi-raspbian
bash

Best,

"In July 2005, after several failed attempts to legalise software
patents in Europe, the patent establishment changed its strategy.
Instead of explicitly seeking to sanction the patentability of
software, they are now seeking to create a central European patent
court, which would establish and enforce patentability rules in their
favor, without any possibility of correction by competing courts or
democratically elected legislators."
