v3.16-rc4 messes up make kernelrelease with additional output

[Russell King - ARM Linux <linux@arm.linux.org.uk>]

3.16-rc3 and all previous versions:

$ make ARCH=arm CROSS_COMPILE=arm-linux- O=/tmp/build/ kernelrelease
3.16.0-rc3+
$

3.16-rc4:

$ make ARCH=arm CROSS_COMPILE=arm-linux- O=/tmp/build/ kernelrelease
make[1]: Entering directory `/tmp/build'
3.16.0-rc4+
$

There are tools which expect kernelrelease to only produce a single
line.  I believe c2e28dc975e (kbuild: Print the name of the build
directory) is probably responsible as this line appears on stdout.

This screws up scripts which do:

        open FH, "$build_cmd kernelrelease $O |" or die $!;
        my $kernelrelease = <FH>;
        close FH;
        chomp($kernelrelease);

or

	version=$(make O=$o kernelrelease)
