cc_test targets fail to build for linux-arm64

[mcevoypeter]

Description

All cc_test targets fail to build when targeting linux-arm64 because of a failure to detect a suitable toolchain. Toolchain resolution for tests apparently differs from library and binary targets, presumably because tests are built for the execution platform rather than the target platform by default.

Reproduction Steps

To reproduce, run the following on an x86_64 machine with Linux and version 12.2.0 of aarch64-linux-gnu-gcc installed:

% bazel build --aarch64_linux_gnu_gcc_version="12.2.0" --host_platform=//:aarch64_linux_gnu_gcc-linux-x86_64 --platforms=//:linux-arm64 --toolchain_resolution_debug='.*' ...
