You just listed two different compilers: do you mean you used a 
prebuilt ldc 1.3 on linux/x64 to build an ldc 1.4 cross-compiler 
on linux/x64 for armhf from source?  If so, maybe you're invoking 
the wrong one, ie you should run ./ldc_build_arm/bin/ldc2 not 
ldc2 when cross-compiling.

Are you patching ldc 1.4 at all?
That old patch linked from the wiki won't work.
