  From: Tom Tromey <tromey@redhat.com>

In C, we can forward declare static structure instances.  That doesn't
work in C++ though.  C++ treats these as definitions.  So then the
compiler complains about symbol redefinition, like:

 src/gdb/elfread.c:1569:29: error: redefinition of ‘const sym_fns elf_sym_fns_lazy_psyms’
 src/gdb/elfread.c:53:29: error: ‘const sym_fns elf_sym_fns_lazy_psyms’ previously declared here

The intent of static here is naturally to avoid making these objects
visible outside the compilation unit.  The equivalent in C++ would be
to instead define the objects in the anonymous namespace.  But given
that it's desirable to leave the codebase compiling as both C and C++
for a while, this just makes the objects extern.

It is a little pity to do so, but I don't know any other better way.
The patch looks good to me.

looks base_breakpoint_ops has been declared in breakpoint.h, so we can
just remove it here.
