Bug#427990: glibc: PIE executables core dumps on hppa

Package: glibc
Severity: important
Tags: patch

start.S file is messing up the paramaters when using the -pie option.
This causes instant segfault on hppa when trying to run an pie executable.

This causes portmap and nscd to break on this arch and maybe many other

Here is a patch that fix the start problem, but all pie programs must
be relinked to fix the segfault.
