Hang on, I am talking rubbish. This is the chain of events:

meson compile --version told me:

     ldc2 -of=mwe mwe.p/dsostub.d.o mwe.p/md_static_import.d.o 
mwe.p/main.d.o -L=--allow-shlib-undefined -link-defaultlib-shared

I added a "-v" to this and reexecuted this manually. This told me 
that the following gets executed:

     /bin/cc mwe.p/dsostub.d.o mwe.p/md_static_import.d.o 
mwe.p/main.d.o -o mwe -Xlinker --allow-shlib-undefined 
-L/opt/ldc2-1.28.0/lib -lphobos2-ldc-shared -ldruntime-ldc-shared 
-Wl,-rpath,/opt/ldc2-1.28.0/lib -Wl,--gc-sections -lrt -ldl 
-lpthread -lm -m64

And that seems to invoke /bin/ld which through 
/etc/alternatives/ld links to /usr/bin/ld.bfd. So that seems how 
I end up with ld.bfd... Meson not to blame, apologies to meson 
:). I might be able to get meson to pass -fuse-ld=ld.gold or lld 
through ldc2 to /bin/cc.
