Hey Thad,
Thanks for catching that: it turns out that we weren't passing -nostdlib to the linker when linking the ELFLoader, so the cross-toolchain's linker was trying to link the ELFLoader against the cross toolchain's libc, but it shouldn't be doing that and it
should instead be using our libmuslc. A fix has been pushed out and you should be seeing it shortly.
Thanks for your patience,
