[PATCH] Patch 2 of 2 for ILP32 aarch64

[Steve Ellcey]

Here is a new version of patch 2. Â I added the one line descriptions
that were missing, fixed the configure.ac problems that Andreas pointed
out (and ran autoconf to make sure they were tested) and changed the
default version in shlib-versions to 2.26.
