Actually that's a question for binutils mailing list. I was researching
that problem some time ago and found that dynamic linker has a switch
'--retain-symbols-file FILENAME' to leave only listed in the FILENAME
names in the SYMBOL TABLE. But according to 'objdump -xstTR' DYNAMIC
SYMBOL TABLE still has all global symbols listed. I'd call it a limitation
of ELF format, which has no a concept of exported symbols.
