-defaultlib/-debuglib are mainly intended to be used for setting 
defaults from the config file. To disable that and only use the 
explicitly specified libraries, you can pass it with an empty argument.

The difference is that DMD parses any `-l` arguments and ignores `lib` 
prefixes, `.so` suffixes and on `.a` suffixes passes `-Bstatic` to the 
linker before the respective `-l` argument.

LDC does not currently implement a way to specifically switch between 
statically/dynamically linking the standard library. You can either 
manually specify `-L-Bstatic`, or have a look at 
https://github.com/ldc-developers/ldc/pull/1305.

Best,
