No.  -Bsymbolic is only relevant at link time.  It does not 
affect the compiler proper.

If you want finer resolution, you have to start playing with
ELF symbol visibility modifiers.  And if you want to use this
on symbols that still need to be seen outside the library
(i.e. most functions), you'll need glibc 2.2.2 or later as
this feature is relatively new.

Moreover, for C++ you'll really need more help from the 
compiler as well, since putting

  asm (".protected _Z6mumble1V");

all over the place with mangled symbols really isn't going
to cut the mustard.
