title: bazel missing dependency declarations for stddef.h and others Ubuntu 18.04
body: <p>I am trying to build an existing project using bazel, but get complains of the form</p>
  
  <pre><code>ERROR: .../BUILD:115:1: Couldn't build file xxx.o: undeclared inclusion(s) in rule '@yyy:
  this rule is missing dependency declarations for the following files included by zzz.c':
  '/usr/lib/gcc/x86_64-linux-gnu/7/include/stddef.h'
  '/usr/lib/gcc/x86_64-linux-gnu/7/include/stdarg.h'
  '/usr/lib/gcc/x86_64-linux-gnu/7/include/stdint.h'
  '/usr/lib/gcc/x86_64-linux-gnu/7/include/stdalign.h'
  </code></pre>
  
  <p>I am just setting up this code base, and I believe that other people can build.
  It seems that I should not have to declare system include paths, especially in other people's code. Other people don't seem to have this problem. Did I inadvertently skip a setup step?</p>
  
  <pre><code>bazel version: 0.19.2
  gcc version: 7.3.0
  clang version: 6.0.0-1ubuntu2 (tags/RELEASE_600/final)
  Target: x86_64-pc-linux-gnu
  OS: Ubuntu 18.04
  </code></pre>
  
  <p>Is there perhaps a .bazelrc file in which I can specify that system headers do not need to be explicitly declared?</p>
