From 673112b192a9494ea96f7daca061b080db5d3977 Mon Sep 17 00:00:00 2001 From: Diego Elio 'Flameeyes' Pettenò Date: Fri, 17 Jul 2009 14:18:07 +0200 Subject: Check for support of -z nodelete LD flag, don't use it unconditionally. On non-GNU, non-Sun linkers, the -z option is often not understood; make sure that the -z nodelete option is usable before making use of it.
