Make gcc default to ARMv7 and Thumb2 on the ARM architecture

Registered by Oliver Grawert on 2009-11-05

We want to build the archive in lucid for the ARMv7 architecture with thumb2 support. The compiler needs to have the proper default settings when building binaies for the armel architecture.

Whiteboard

[asac 02-12-09]: taking over assignments for the outstanding TODOs.
[asac 08-01-10]: we will append thumb2 to the version to ensure that they get auto synched
[asac 08-01-10]: lib tests will get run after alpha-2
[asac 08-01-10]: the rebuild will happen after DIF -> moving to alpha-3
[asac 08-01-10]: implicit-it is in toolchain by default
[asac 08-01-10]: user-space regressions so far are ftbfs and bugs filed with thumb2 tag
