rpm: Use link time check for libssp

-fstack-protector needs libssp to link with
so when checking for this option support we
need to find if libssp is staged in root file
system

+Some options checked in this loop are needing linking to find out
+if the option can be used or not e.g. -fstack-protector which needs
+libssp to be staged and available for compiler to link against
+Therefore we change the compile only check to compile and link check
