[Buildroot] [PATCH 1 of 3 for 2014.08] manual/getting started: minor improvements to 'Using Buildroot' section

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

This patch renames the section 'Using Buildroot' into 'Buildroot quick
start' as real details about Buildroot usage will be in the User Guide
rather than in 'Getting Started'.

Additionally, add a cross-reference to the section about configuring
Buildroot.
