Really needed? wasm will most likely never support shared druntime/Phobos, nor dynamic-compile.

Passing -link-defaultlib-shared when compiling with -defaultlib= or -betterC still passes -rpath making it fail. + it makes #4848 fail because I no longer strip the -link-defaultlib-shared that comes from -DBUILD_SHARED_LIBS=... in the wasm switches.

Of course I could add it back but it seems more reasonable to ignore -link-defaultlib-shared, in my opinion at least

llvm::StringRef rpath = ConfigFile::instance.rpath();
if (!rpath.empty())
addLdFlag("-rpath", rpath);
