160# We cannot currently enable the stack protector for rtld as it runs
161# before libc initializes, which is where we always enable the stack
162# protector values. Because rtld is likely on an alternate link map and
163# links in the relevant portions of libc through libc_pic.a, there is
164# probably a path to enabling an rtld specific version of the stack
165# protector.
166#
167# As a result, this currently disables the stack protector in two
168# related targets which really could use it. These are libconv and libc.
169# Both of these end up building position-independent archive libraries
170# that are directly linked into rtld. This situation can and should be
171# improved.
