Can you provide details of the errors seen and toolchain versions.
I notice we don't have any CI support for Haiku right now, nor
any recipe in tests/vm/ for enabling users to setup a VM with
Haiku installed. This very much makes Haiku a second class
citizen right now in terms of QEMU's supported platforms, with
no expectation of whether it'll work at any point in time.
