Comment (by kencu):

 And just to make it a little more difficult, i386-darwin9-apple fails with
 a completely different error:
 {{{
 :info:build ld: warning: could not create compact unwind for
 std::basic_string<char, std::char_traits<char>, std::allocator<char>
 >::replace(unsigned long, unsigned long, char const*, unsigned long):
 dwarf uses DW_CFA_GNU_args_size
 :info:build ld: illegal text-relocoation (direct reference) to
 (global,weak) loc_list_hasher::equal(dw_loc_list_struct const*,
 dw_loc_list_struct const*) in libbackend.a(dwarf2out.o) from anon in
 libbackend.a(dwarf2out.o) for architecture i386
 :info:build collect2: error: ld returned 1 exit status
 }}}
