[PATCH 2/6] Undefine redirections after long double definition on __LDBL_COMPAT [BZ #23294]

[Paul E Murphy]

My only contribution to this patch is to fix the merge conflict in the 
Makefile while rebasing.

Note, this does address the feedback from Joseph [1] about adding a test 
which will fail without this change.  I Have verified the test does fail 
without the change.

If there are no further requests or objections for this patch, I would 
like to commit it friday.  It is necessary to for functional redirection 
support in ldbl-128ibm-compat.
