The biggest issue to solve here is the rest of the toolchain (linker, 
system libraries, …). LDC's part can easily be done by adding a small 
piece of code to the config file handling such that different sections 
are matched depending on the chosen target (where you can then set 
library lookup paths for druntime/Phobos, the GCC excecutable to use for 
cross linking, etc.).

Unfortunately I'm not at DConf this year, but I'd be happy to help out 
with any questions you might have implementing something like that.
