Current trick to pick up GNU assembler minor version does not work with the
latest binutils (2007-03-01 or later) due to ${PKGVERSION} now default to
"(GNU Binutils) ".

  $ sde-as --version |grep "GNU assembler"
  GNU assembler 2.15.94 mipssde-6.02.02-20050602
  $ sde-as --version |grep "GNU assembler" |awk '{print $3}'
  2.15.94
  $ sde-as --version |grep "GNU assembler" |awk '{print $3}' |awk -F. '{print $2}'
  15
  $
  
  $ mips-linux-as --version |grep "GNU assembler"
  GNU assembler (GNU Binutils) 2.18
  $ mips-linux-as --version |grep "GNU assembler" |awk '{print $3}'
  (GNU
  $ mips-linux-as --version |grep "GNU assembler" |awk '{print $3}' |awk -F. '{print $2}'
  (no output)
  $

As a result of above, you'll see many noises with such binutils:

This patch simplifies the trick and makes it work with both versions of gas.
I also replace an expensive `awk (or gawk)' with `cut'.

Fixed by moving these two functions forward.

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.

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.

All transformations are of the form:
Before:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)
