Comment (by jeremyhu@…):

 Looking at src/ld/OutputFile.cpp, it looks as if SUPPORT_ARCH_x86_64
 wasn't defined for the bad build ... I think that would cause all those
 missing C++ class name strings.

 But that doesn't make sense since SUPPORT_ARCH_x86_64 is supposed to be
 defined in configure.h which is created by create_configure during ld64's
 build, and it uses the value of RC_SUPPORTED_ARCHS, which should include
 x86_64 (and seems to based on the output of ld -v for the bad build ...
 puzzling)

 I'll need to wait for my builds to finish to take a look at this more...
