Subject: [029/197] sh: Fix FDPIC binary loader

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Andrew Stubbs <ams@...esourcery.com>

commit d5ab780305bb6d60a7b5a74f18cf84eb6ad153b1 upstream.

Ensure that the aux table is properly initialized, even when optional
features are missing. Without this, the FDPIC loader did not work.
