That in conjunction with the -O0 warning seems to me to be insane.

OK, can you write a patch that simply removes the -Wp,-D_FORTIFY_SRC
option from all testsuite builds?  I don't see any reason to make the
gold testsuite more complex by sometimes using CXXCOMPILE and
sometimes using CXXCOMPILE_NFORTIFY.  The use of _FORTIFY_SRC is
irrelevant for the gold testsuite.

Also needs a comment explaining why this is necessary.
