See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90441#c25

"I fear this is the libbfd dwarf reader simply not coping with
DW_AT_abstract_origin in other CUs, being confused as to which
abbrev section it needs to look into (probably using that of
the refering CU instead of the referred to one)."

The problem is that the code in dwarf2.c:find_abstract_instance only looks over
the chain of CUs already parsed.  The one pointed at by DW_FORM_ref_addr hasn't
yet been parsed.
