Andi, did you report a bug? Does the non-libbfd stuff work? Yes, as
every distribution has shipped it since binutils went to GPLv3 (in
2007?). While I don't want LLVM stuff not to work, bugs happen, libbfd
is license incompatible with GPLv2 and maintaining it in the source
tree is a burden. When something doesn't work, create a test to repeat
the issue and then we can make it work and ensure it doesn't break
again. In general I've not had issues with the LLVM code.
Thanks,
Ian
