Shinya Kuribayashi 7e1d884b7c [MIPS] cpu/mips/config.mk: Fix GNU assembler minor version picker
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'.
