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:
make -C cpu/mips/

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