Fix for SIGBUS error on MIPS64 with N64 ABI

When accessing errno, a per thread variable, from _stdio_init
a SIGBUS error happens. This change fixes the wrong relocation
and debug output.

ARC port to uClibc

For this port, I would like to give due credit to:

- Folks from Codito technologies (Sameer, Amit, Kanika, Ramana,...)
   who did the very first port

- ARC UK from 2007-2009 (Joern, Irfan, Khurram, Phil...

- Late Brendan Kehoe (may he RIP)

libc/sysdeps: commonize ret_ERRVAL

* Add a common ret_ERRVAL definition

* Remove ret_ERRVAL from architectures using the common 'ret'

* Add 'undef' to architectures that need a different return instruction

* Add '#include <common/sysdep.h>' to cris and ia64 that were missing it

librt: fix mq_timed{send,receive} return instructions

Not all architectures use 'ret' as function return instruction. For example,
xtensa usually uses 'retw'. Use the ret_ERRVAL arch dependant macro instead.

inet: Fix threaded res_init

In a multi-threaded application where res_init() was called either
directly or implicitly, getaddrinfo() and others failed to add the
DNS search domain to hostnames.

This problem made it not possible to look up a hostname without its
domain appended.

The problem is caused by res_sync_func() overwriting the configuration
read by __open_nameservers() immediately after it is read.

The suggested solutin is to disable res_sync_func() while reading name
server configuration in res_init().

ldso: ARC: tweak whitespace some more

Use spaces instead of tabs in the table to accomodate different tab
