Right:) The only reason that GNU ld needed -Bsymbolic-functions is to avoid collision with copy relocations.
In a -fpie/-fpic world, we should not see copy relocations from C/C++ code but GCC x86-64 still has the `HAVE_LD_PIE_COPYRELOC` issue😠(https://gcc.gnu.org/legacy-ml/gcc/2019-05/msg00215.html) @hjl.tools
