Detailed error log

I'm trying to build Mesa against libllvm10, using static linking option for
llvm:

    -Dshared-llvm=false

That's done on Debian testing, gcc 9.2.1 with llvm build from
http://apt.llvm.org/unstable/pool/main/l/llvm-toolchain-snapshot/

I get such error when it's building libvulkan_radeon.so


/usr/bin/ld: /usr/lib/llvm-10/lib/libLLVMAMDGPUDisassembler.a: error adding
symbols: archive has no index; run ranlib to add one


See more detailed error attached. Is it a problem with this llvm build or
something else?
