I decided it was time to start pulling out Adam Ruppe's
embedded programming guide, and as a decidedly non-embedded
programmer, the instructions here:
http://wiki.dlang.org/Bare_Metal_ARM_Cortex-M_GDC_Cross_Compiler
... are not something I'm confident in just following (not
least because e.g. certain scripts are provided without much
indication of what they should be called, where they should be
placed, or how to use them).
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.
