8 years ago I'm going to guess that the linker on your system has a different output format for the -t flag ("-Wl,-t" in the Makefile). Can you send the contents of bin/build/llvm_objects/list in the Halide directory you are building in?
Also the output of "ld --version" or "ld -v" might help.
I think we are now at the point where this mechanism has shown enough flakiness due to different linkers producing different output that we should probably find another way to make the list of LLVM object files, but hopefully we can get a fix for this specific issue more quickly.
Thanks, -Z-

I'm building using the Makefile. It fails when trying to run extract.sh, here are the first few lines of that script:
ar x -lLLVMPowerPCDisassembler ; mv llvm1 /usr/lib64/libLLVMPowerPCDisassembler.so ar x -lLLVMPowerPCCodeGen ; mv llvm2 /usr/lib64/libLLVMPowerPCCodeGen.so ar x -lLLVMPowerPCAsmParser ; mv llvm3 /usr/lib64/libLLVMPowerPCAsmParser.so ar x -lLLVMPowerPCDesc ; mv llvm4 /usr/lib64/libLLVMPowerPCDesc.so ar x -lLLVMPowerPCInfo ; mv llvm5 /usr/lib64/libLLVMPowerPCInfo.so
And the error (there lots of these, I assume every line in extract.sh fails:
