Add an x86_64-grtev3-linux-gnu target.

For GRTE v2, we use the value of $with_sysroot to conditionally include spec
file changes.  This is inconsistent with what we do for other architectures
like ARM, and it's less flexible since (a) the feature machinery is really
designed to key off $target and (b) we're inferring fundamental things from
incidentals.

This should make it easier to add further GRTE-specific features (patches
forthcoming) and has the added bonus of allowing us to differentiate between
native bootstrap test failures and Crosstool build failures.

I will be submitting this to the google/integration branch and integrating to
google/main and google/gcc-4_7.
