Remove build failure with USE_BAZEL_ANALYSIS usage

This verification was present to ensure that users previously using
USE_BAZEL_ANALYSIS=1 realized the change in usage. But this is now dead
code; USE_BAZEL_ANALYSIS=1 will be a complete no-op after this CL.

Test: USE_BAZEL_ANALYSIS=1 m nothing  (and verified this behaves as m
nothing)
