Log:
lldb: workaround to permit cross-arch core file debugging
FreeBSD core files have no section table and thus LLDB's OS and vendor
detection logic does not work. If we encounter such an ELF file, update
an unknown OS to match the host.
This is not really the correct way to handle this, but more extensive
rework of ObjectFileELF will be needed and this change restores cross-
arch core debugging until that can be completed.
