wrong compiler options used when cross compile use bazel

[xiedeacc]

from document https://abseil.io/docs/cpp/platforms/platforms, abseil support aarch64, but abseil will generate wrong compiler option when cross compile for aarch64.

oops, it seems abseil-cpp only support --cpu config, not support --platforms option, so request support --platforms option, for --cpu has deprated by bazel official

    name = "linux_aarch64",
    match_all = [
