This race is when building scripts in the staged kernel tree (sysroot). To prevent this, we promote the do_make_scripts() function to a task, which we protect by a lock. Tip on how to make this work was received by Richard in [1]. To avoid new problems, introduced by this promotion, we make this new task depend on do_populate_sysroot from the modules dependencies (i.e. virtual/kernel). This patch has been extensively tested on the 2011-1 release branch, on a custom ARM-machine and distro with several external modules.
