exception: ensure base exception vtable is non-hidden

I found that when building this library under Yocto, `-flto=auto` is
used by default and the vtable for the exception class ends up becoming
hidden (since there are no non-pure/non-inline functions).  I've tried
using `__attribute__((visibility("default")))` with no luck.  The only
thing which seems to work is defining some non-inline function to force
the vtable to be emitted.
