Now we load $gp with _GLOBAL_OFFSET_TABLE_, but this is incorrect use.
As a general principle, we should use _gp for $gp.
Thanks to linker script's help we fortunately have _gp which equals to
_GLOBAL_OFFSET_TABLE_. But once _gp gets out of alignment, we will not
be able to access to GOT entires, global variables and procedure entry
points. The right thing to do is to use _gp.
This patch also introduce a new symbol `.gpword _GLOBAL_OFFSET_TABLE_'
which holds the offset from _gp. When updating GOT entries, we use this
offset and _gp to calculate the final _GLOBAL_OFFSET_TABLE_.
This patch is originally submitted by Vlad Lungu <vlad@comsys.ro>, then
I made some change to leave over num_got_entries.

* Patches by Kenneth Johansson, 25 Jun 2003:
- major rework of command structure
(work done mostly by Michal Cendrowski and Joakim Kristiansen)
instead CFG_MONITOR_LEN is now only used to determine _at_compile_
_time_ (!) if the environment is embedded within the U-Boot image,
or in a separate flash sector.
* Cleanup CFG_DER #defines in config files (wd maintained only)
Add IDMA example code (tested on 8260 only)
* Add support for Purple Board (MIPS64 5Kc)
* Add support for MIPS64 5Kc CPUs
* Fix missing setting of "loadaddr" and "bootfile" on ARM and MIPS
* Patch by Denis Peter, 04 Apr 2003:
- update MIP405-4 board
* Patches by Denis Peter, 03 April 2003:
- fix PCI IRQs on MPL boards
- fix two more un-relocated pointer problems
* Fix behaviour of "run" command:
- print error message iv variable does not exist
- terminate processing of arguments in case of error
* Patches by Peter Figuli, 10 Mar 2003
- Add support for BTUART on PXA platform
