OK, thanks.  I'll put this into a patch this weekend.  What's going on 
is that while I'm not sure where -fstack-protector is coming from (but 
it's a useful flag), as you saw, 'ld' chokes on it.  But for linking you 
shouldn't really ever invoke ld directly but rather via gcc, so passing 
LD=${CCLD} overrides perl's makefiles and we invoke gcc as the linker 
and it handles the flag right in this case.
