Ensure redhat hardening flags didn't leak into the tarball.

Several people reported that the tarballs didn't work on
non-Fedora/RHEL platforms.  The reason is that the 'redhat-hardened'
LDFLAGS managed to leak into the build-aux/ltmain.sh file (part of
libtool).

This happened because of a bug in Fedora's libtool:
https://bugzilla.redhat.com/show_bug.cgi?id=1214506

Add a check to ensure this cannot happen in future.
