On Gentoo yes its called crossdev[1]. You can have a build system/toolchain for any arch you need to make an entire system or binaries for and them over to what ever device. Use a very powerful host system of a completely different arch, like x86_64 to build armv7 and others. I did this a while back to make tun/tap kernel drivers for an android system. I also used it a very long time ago using docs in vapier's devspace[2] before it was documented else where. That was when I got my first x86_64 system and there were no 64bit pre-compiled kernels or livecds at the time. So I used a i686 Gentoo system to make a x86_64 kernel. The best part of that last story, I got kernel patches from SuperMicro because x86_64 stuff was so new. The SuperMicro kernel patches were made against a Gentoo kernel. 1. https://wiki.gentoo.org/wiki/Cross_build_environment 2. http://dev.gentoo.org/~vapier/CROSS-COMPILE-HOWTO -- William L. Thomson Jr.
