Currently compile_bazel_dist_test is doing a lot (regular compile + direct bazel gcc compile + direct bazel clang compile) without separating the steps into different tests. This makes it unclear as to which step actually failed without digging into what its doing.

bazel_compile.sh also doesn't log out the command line invocation it performs

While here, also update integrate_bazel's command line log to combine the list into a string you can copy-paste into the command line for ease of use. https://github.com/10gen/mongo/blob/master/site_scons/site_tools/integrate_bazel.py#L286
