build_arch:
description: |
Specifies architecture of the build sandbox.
This defaults to $(uname -a). On platforms where the Baserock architecture
name doesn't match the Linux architecture name, you need to manually
specify the Baserock architecture name.
You can also use this to build for a different architecture provided your
host can execute binaries for that architecture. For example, you could
run an x86_32 build on an x86_64 machine by setting `build_arch=x86_32`
and `arch=x86_32`.

arch:

Specifies host and target architecture for output binaries.
Usually this should match build_arch. If it differs, a cross compile
will happen up to the gnu-toolchain/stage2.bst stack. Beyond this,
cross compilation isn't supported.
For instructions on how to bootstrap a new architecture, see:

# This causes debug stripping to just not happen, which makes the stage3
