What makes you think the toolchain is misbehaving?  Your visibility
command line options affect the code you are compiling, but you of
course are linking against other object files as well.  Maybe all the
symbols that seem unexpected to you come from libcryptopp.a or libc?

Seems good to me.  You asked ld to exclude All.a symbols.
