Yes.

Yes, I build master ldc some time ago (before 1.3.0 release) and 
it have version 1.4.0 (it's not master now, I say master because 
it was not a tag and I don't know why developers names it 1.4.0) 
and it's very long time building. Now I only try using builded 
libs. If they did not work, I must be rebuild they. But they 
work! And working druntime and phobos isn't a question.

Because rpi2 have 1GB RAM, building gtk-d need more 1.6 GB RAM.
For code without gtk-d building is very slow.

I try build my soft on rpi.

Main question is how to specify dir with ARM version of druntime 
and phobos and remove default dir from call extern gcc compiler? 
Default dir is /usr/lib64 and it contains druntime and phobos 
(x86_64). Additional dir not scans because build fails while 
trying loading existing x86_64 libs.
