Subject: [GIT PULL] atomic regeneration (was "[PATCHv2] locking/atomics:
 build atomic headers as required")

Hi Ingo,

Peter suggested you'd prefer a pull request for the atomic scripting rework, so
hopefully this is sufficient. :)

The rework means that the atomics are now rebuilt as-required. The headers are
built in parallel, along with other early build steps, so this isn't as
noticeable on a reasonably powerful machine. Once the headers are built,
they'll only be regenerated when their dependencies change, and can be cleaned
with a mrproper.

Thanks,
Mark.
