[PULL 31/31] linux-user: Remove the deprecated ppc64abi32 target

From: Thomas Huth <thuth at redhat.com>
It's likely broken, and nobody cared for picking it up again
during the deprecation phase, so let's remove this now.
Since this is the last entry in deprecated_targets_list, remove
the related code in the configure script, too.
