libssp + using glibc stack protector in cups broke

[ghost]

although cups would build and install, any dependent programs seemed to fail like gutenprint-libs with a linker error symbol __stack_chk_guard not found:

From what I can gather, normally the gcc compiler should do 'the right thing' when -fstack-protect is passed, but thanks to a hint gleaned here (http://gcc.gnu.org/ml/gcc-patches/2005-07/msg00066.html)
in addition to -lssp_nonshared, -lssp needs to be there as well.

Apparently a compiler problem, and a moving target, because I noticed that the pkgsrc Makefile for cups had this entry for SunOS: CONFIGURE_ENV+= LIBS_SSP=-lssp_nonshared

after applying the following, (and deinstalling fully cups), I was able to rebuild cups and get over this problem in gutenprint:

jperking disabled the stack-protector for Perl earlier:
