[PATCH v2] arago.conf: Choose the proper toolchain by default depending on SOC_FAMILY

[PATCH v2] arago.conf: Choose the proper toolchain by default depending on SOC_FAMILY

[Franklin S. Cooper Jr]

* Linaro toolchain does not support ARM9 architecture.
* The Arago toolchain should be used if an ARM9 based SOC_FAMILY is being built.
* Introduce a new variable TC_SANE_DEFAULT that determines which toolchain to
  use depending on the machine's SOC_FAMILY.

Changes compared to v1:
Use seperate variable TC_SANE_DEFAULT suggested by Denys.
This seperate variable avoids any Python overhead since the value is evaluated
only once.
This still allows the TOOLCHAIN_BRAND to be overridden in the local.conf file.
