Fix LD_BIND_NOT and LD_PROFILE on ia64

[Roland McGrath]

The 2.3 backport patch is of course useful when it's fixing bugs.  In
future, please indicate in the subject line when a patch is not intended
for the trunk.  As Ulrich said, it will have to be integrated in the trunk
first before a backport version could be considered for the branch.  Once
it's settled what the trunk code will look like to address the issues, and
if people's production branches based on 2.3 are using the fix, then it can
be considered for the release branch.


Thanks,
Roland
