You're trying to use bfd as your linker, and I think that only exists on the Linux version of the NDK. Maybe try looking somewhere under ldc_android/android_ndk/toolchains/x86_64-*/prebuilt/windows-x86_64/bin to see what linkers are shipped with your NDK, and specify that instead?

On Linux, I see a bunch of binaries named x86_64-linux-android-*, including *-ld, *-ld.bfd, *-ld.gold, which are the 3 linkers that can be used via -fuse-ld=bfd, -fuse-ld=gold, etc..  I'm not sure how it works on Windows, but there should be corresponding binaries that might give a hint as to what's the correct -fuse-ld=... option you need to use.

Here I documented some of the quirks I've hit during android prototyping.
Works like this, no idea if it is still up to date though.

Thank you mate, got it working now. With the ld linker.

Found ld linker as you described.
Slapped on the --linker=ld flag and now everything is working. Thanks! :D

Or atleast that's what I thought, it links, but won't run, apparently bfd linker is required. So I installed that one.
