Those instructions came from my personal script that I use to
build GDC from time-to-time.  It's all one script.  I broke it up
in the wiki in an effort to explain the process so one could
adapt it to their needs.  Here's the entire script I use.  I run
it from within my ~/gdc folder and it installs to my
~/gdc-arm-none-eabi folder.

This is for ARM Thumb (ARM Cortex-M), not ARM9, ARM11, ARM
Cortex-A hardware.  It is for the barest of bare-metal (no libc,
no D runtime, no phobos, etc...), intended for those who want to
actually create a D runtime.
