gcc (4.1) hardcodes both -lssp and -lssp_nonshared when
-fstack-protector is passed.
Instead of letting the linker decide on whether you are using and libssp.a they felt the need to explicitly identify them
as different.
My approach was to use the patch below and rename
lib/libssp_nonshared.a to lib/libssp.a so that if for any reason I
needed libssp.a (such as gcc -static) I would be able to do such and
the linker would know what to do.
