GNU compilers generate a `DW_AT_containing_type` pointing to either the base
class or it self if no base class to point to for `DW_TAG_interface_type` tags.

This produces the following error on LLDB while trying to read DWARF:

error: a.out {0x00000287}: unhandled type tag 0x0038 (DW_TAG_interface_type),
please file a bug and attach the file at the start of this error message
