Current trick to pick up GNU assembler minor version uses a dot(.) as a
delimiter, and take the second field to obtain minor version number. But
as can be expected, this doesn't work with a version string which has
dots more than needs.

Here's an example:

$ mips-linux-gnu-as --version | grep 'GNU assembler'
GNU assembler (Sourcery G++ Lite 4.2-129) 2.18.50.20080215
$ mips-linux-gnu-as --version | grep 'GNU assembler' | cut -d. -f2
2-129) 2
$

This patch restricts the version format to 2.XX.XX... This will work
in most cases.

$ mips-linux-gnu-as --version | grep 'GNU assembler' | egrep -o '2\.[0-9\.]+'
2.18.50.20080215
$ mips-linux-gnu-as --version | grep 'GNU assembler' | egrep -o '2\.[0-9\.]+' | cut -d. -f2
18
$

This reduces the build time by ~10%. Here's the gth2_config example.

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}'

  $
  
  $ 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'.

Patch by Thomas Lange, 10 Aug 2005

Incorrect gcc options (big endian -BE switch) were used for
dbau1550_el which is a little endian build; also get rid of reference
to non-existant cpu/mips/little/liblittle.a library

* Adjust MIPS compiler options at run-time depending on tools version
  ("-march=4kc -mtune=4kc -Wa,-mips_allow_branch_to_undefined" for new,
  "-mcpu=4kc" for old tools)

  - remove trailing white space, trailing empty lines, C++ comments, etc.
  - split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)

* Patches by Kenneth Johansson, 25 Jun 2003:
  - major rework of command structure
    (work done mostly by Michal Cendrowski and Joakim Kristiansen)
