Questions relating to the use of ARM microchip architecture with Ubuntu

ARM, originally Acorn RISC Machine, is a family of reduced instruction set computing (RISC) instruction set architectures for computer processors, configured for various environments, developed by British company ARM Holdings.

A RISC-based computer design approach means ARM processors require significantly fewer transistors than typical complex instruction set computing (CISC) x86 processors in most personal computers. This approach reduces costs, heat and power use. Such reductions are desirable traits for light, portable, battery-powered devices—​including smartphones, laptops, tablet and notepad computers, and other embedded systems. A simpler design facilitates more efficient multi-core CPUs and higher core counts at lower cost, providing improved energy efficiency for servers.

Ubuntu begin releasing for ARM with Ubuntu 7.10 (Gutsy Gibbon).

How to cross compile for ARM?

How do I set up GCC for cross compiling for the ARM processor? The host would be on x86_64 ( AMD64 - Ubuntu 12.04 ) and the target would be ARM (Raspberry Pi as well as Pandaboard - will do separate compilations for each)?
