I actually tried to get a gdc build a week or two ago for a cortex-a8 
using ng-crosstools-linaro. I managed to get up to compiling druntime, 
which then was pointing to a commit prior to

https://github.com/D-Programming-Language/druntime/commit/541e7ba00d5e75426bb677d7f7548a47a904551f

so it failed. Then I figured I'd wait for your fixes.
