fix bazel build

[mikedanese]

Build appears to be broken on HEAD

Not sure if this is the best way to fix :)

Doh, I just cut a release! :) No matter, we'll get this fixed (waiting for dzc to comment on that) and then do a follow-up release.

[davidzchen]

This PR looks good but what's odd is that bazel build //cmd:jsonnet works fine for me with Bazel at HEAD (as in Bazel HEAD). Which version of Bazel are you running and on which OS?

[mikedanese]

I'm running the most recent release. It looks like std.jsonnet.h is not included in the sandbox.

$ bazel version
Build label: 0.2.0
Build target: bazel-out/local_linux-fastbuild/bin/src/main/java/com/google/devtools/build/lib/bazel/BazelServer_deploy.jar
Build time: Tue Feb 23 13:08:29 2016 (1456232909)
Build timestamp: 1456232909
Build timestamp as int: 1456232909
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 15.10
Release:        15.10
Codename:       wily
$ uname -a
Linux ubuntu 4.2.0-30-generic #36-Ubuntu SMP Fri Feb 26 00:58:07 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

looking at the previous rule, it seems like it should have worked...

[sparkprime]

I also had this on my work laptop:

$ bazel version
Build label: 0.1.2
Build target: bazel-out/local_linux-fastbuild/bin/src/main/java/com/google/devtools/build/lib/bazel-main_deploy.jar
Build time: Fri Dec 4 23:13:21 2015 (1449270801)
Build timestamp: 1449270801
Build timestamp as int: 1449270801

@davidzchen did you try on a fresh clone?

[davidzchen]

Interesting. This reproduces on Linux but not on OS X. Let's go ahead and merge these changes. I'll try to isolate a test case and send a bug report to Bazel.

LGTM

[sparkprime]

We could really use a travis rule for bazel builds :)

[davidzchen]

I'll set that up :)
