Authentication-results: sourceware.org; auth=none

The attached change is preparation for a patch to optimize indirect calls.  For this, we need to a
valid function pointer for fixup in __canonicalize_funcptr_for_compare.  The least-significant two
bits of the pointer should have the value 2, not 3, when the pointer points to a function descriptor.

Tested on hppa-unknown-linux-gnu and committed to trunk.
