Description of the problem / feature request:

Bazel should support compiling 32-bit c++ build targets on windows.

Feature requests: what underlying problem are you trying to solve with this feature?

I need to compile c++ binaries that run on 32-bit windows.

Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

Tried specifying bazel build ... --cpu x86_32 and bazel build ... --cpu i386 (from bazelbuild/platforms), and both errored out with something like:

ERROR: C:/users/username/_bazel_username/pkyimvir/external/local_config_cc/BUILD:47:1: in cc_toolchain_suite rule @local_config_cc//:toolchain: cc_toolchain_suite '@local_config_cc//:toolchain' does not contain a toolchain for cpu 'x86_32'

What operating system are you running Bazel on?

Windows 10 / Windows 2019

What's the output of bazel info release?

release 2.1.0

Have you found anything relevant by searching the web?

Found claims on stackoverflow that bazel does not support this, and could not find another github issue specifically requesting it.
