glibc does not use this option.  ABI checking in glibc works on binaries 
via objdump -T.  linknamespace tests do use -aux-info to list functions 
exported by a header, and would find it useful to be able to list exported 
variables as well, but while the output of -fdump-translation-unit 
includes variables it didn't seem at all convenient to parse for that 
purpose.
