ERROR: /home/lenger/.cache/bazel/_bazel_lenger/e744db622218e02ee1e2cbf3b8750f17/external/nsync/BUILD:402:13: Configurable attribute "copts" doesn't match this configuration (would a default condition help?).

Solution:
vim /home/lenger/.cache/bazel/_bazel_lenger/e744db622218e02ee1e2cbf3b8750f17/external/nsync/BUILD

Add a default conditions there as marked as red line below:

NSYNC_OPTS_GENERIC = select({
    # Select the CPU architecture include directory.
    # This select() has no real effect in the C++11 build, but satisfies a
    # #include that would otherwise need a #if.
