I would try to use the ldc-build-runtime tool to cross compile to 
my Raspberry Pi (From Windows). But by reading this wiki page 
"https://wiki.dlang.org/Building_LDC_runtime_libraries" it is not 
clear for me what to do.

What is already working: Executing this command seems to finish 
without error:
--ldcSrcDir "ldc-1.4.0-beta1-src" --ninja

But I think I have to call this command with specific parameters 
for the Raspberry Pi. Where do I find this parameters?

Kind regards
