Track and Build the Tip Toolchain
Today we wait nearly the entire month to integrate a new toolchain. This can cause a great deal of risk and stress at the end of the cycle when we attempt to integrate the new toolchain. To derisk and destress the end of cycle crunch, it would be useful to simply build and track tip.

Notes:
[pfalcon 2011-10-04] Proposed implementation:
Add build config param (TBD) which will produce toolchain tarball without time/ver-stamps. Then, latest good build will be accessible with "permalink" like https:/
[pfalcon 2011-10-05]
Ok, config param is TOOLCHAIN_TARBALL, which allows to specify any (static) tarball name, which is the most flexible way it seems.
Done: https:/
I guess it makes no sense to apply that to 4.5 toolchain build - it's not used in such config, and keeping timestamped builds is a boon.
[pfefferz]
It will be useful to be able to keep local workaround patches on our git to ensure that the toolchain can be used while more perminate changes are sent to the toolchain group.

Headline:
Linaro's Android distribution can now base builds off a tip toolchain build
Acceptance:
A reference to the tip toolchain build that we can reference in daily builds and a way to map that reference to the particular build that its referring too.
