The linker split PKGDEF into (prefix, name, def) pairs,
and defines def to begin after a space following the identifier.
This is totally wrong for the following export data:

        func "".FunctionName()
        var SomethingCompletelyUnrelated int

The linker would parse
    name=`"".FunctionName()\n\tvar`
    def=`SomethingCompletelyUnrelated int`
since there is no space after FunctionName.

Our source no longer needs these flags set to build cleanly using clang.

Tested with

* Ubuntu clang version 3.0-6ubuntu3 (tags/RELEASE_30/final) (based on LLVM 3.0) on i386
* clang version 3.2 (tags/RELEASE_32/final) on amd64 cross compiling all platforms

ratio isn't 1x1.

Fixes #4259.

The test data was generated by
cjpeg -quality 50 -sample 2x2 video-005.gray.pgm > video-005.gray.q50.2x2.jpeg
cjpeg -quality 50 -sample 2x2 -progressive video-005.gray.pgm > video-005.gray.q50.2x2.progressive.jpeg

similarly to video-005.gray.q50.* from
http://code.google.com/p/go/source/detail?r=51f26e36ba98
the key difference being the "-sample 2x2".

This proposal updates the dashboard builder to avoid relying on the (soon to be removed) support for using go get to download to $GOROOT. The result is

GOROOT=$WORKSPACE/go
GOPATH=$WORKSPACE

bytes.Equal is simpler to read and should also be faster because
of short-circuiting and assembly implementations.

Change generated automatically using:
  gofmt -r 'bytes.Compare(a, b) == 0 -> bytes.Equal(a, b)'
  gofmt -r 'bytes.Compare(a, b) != 0 -> !bytes.Equal(a, b)'
