I've updated ldc master to use Yuxuan's druntime port, which 
means the upcoming ldc 1.8 release will likely be a viable 
Alpine/Musl cross-compiler out of the box, provided you give it a 
C/Musl cross-compiler/linker to work with, by using the bundled 
ldc-build-runtime tool:

https://wiki.dlang.org/Building_LDC_runtime_libraries

Cross-compiling has not been tested however: do people normally 
cross-compile to Alpine containers or build their software in 
Alpine itself?  If the latter, building ldc from master on 
Alpine/x64 3.7.0 passes all of the druntime/phobos stdlib unit 
tests but one, so you're good to go there, as long as you don't 
need a pre-built binary. Maybe we'll put one out for ldc with the 
upcoming 1.8 release.
