PATCH 1/1 external-toolchain: add Sourcery CodeBench ARM 2012.09

I've added the "depends on BROKEN" because this toolchain breaks linux kernel arm builds:
"arch/arm/lib/copy_template.S:247: Error: selected processor
does not support ARM mode `ldralt r4,[r1],#4'"

PATCH 1/1 external-toolchain: add Sourcery CodeBench ARM 2012.09

Quoted 4 lines · Fabio Porcedda

I've added the "depends on BROKEN" because this toolchain breaks linux kernel arm builds:
"arch/arm/lib/copy_template.S:247: Error: selected processor
does not support ARM mode `ldralt r4,[r1],#4'"

Then why would we add support for that toolchain to buildroot?

Regards,
Arnout

You are right, that toolchain it's not useful to buildroot. At least that email can be useful as an advice for who want to use that toolchain with buildroot.

I've opened a new discussion about this bug on the Mentor's Forum:
