Clang has a bunch of complicated logic to find the correct assembler
if it's installed (in this case I'd expect "msp430-unknown-elf-as").
It's quite possible LDC doesn't have this since its main targets use
the integrated-assembler. Your errors certainly look consistent with
the macOS system "as" being called on ELF MSP430 output.

I know that in Clang you can add "-###" so that Clang will tell you
the exact commands it would run (or -v to both tell you and do it).
I'd hope LDC has some equivalent.
