{param overview} 
An <code>ndk_library()</code> is used to define a set of C/C++ files,
an <code>Android.mk</code> and an <code>Application.mk</code> file that
are used by the NDK's <code>ndk-build</code> tool to generate one or more shared
objects.

  {param desc}
  Array of strings passed verbatim to <code>ndk-build</code>. Normally
  this is not needed, but in some cases you may want to put something
  here. For example, this can be used to build the libraries in debug
  mode (<code>NDK_DEBUG=1</code>) or set the number of jobs spawned by
  {sp}<code>ndk-build</code> (by default, the same as the number of
  cores).

  {param desc}
  Normally native shared objects end up into a directory in the root of the APK
  named <code>lib/</code>. If this paratemer is set to <code>True</code>, then
  these objects are placed in <code>assets/lib/</code>. Placing shared objects in
  a non-standard location prevents Android from extracting them to the device's
  internal storage.

{param furtherexp}

An <code>android_binary()</code> that includes this library will
aggregate all of the native shared objects into a directory in the
root of the APK named <code>lib/</code> or <code>assets/lib/</code>.
<p>
Unlike the default invocation of <code>ndk-build</code>,
{sp}<code>buck</code> will put all intermediate files and build output
into a subdirectory under <code>buck-out/gen</code>.
<p>
Also, because <code>ndk-build</code> and <code>Android.mk</code> do not
expose the necessary dependency information, <code>buck</code> assumes
that all files with the following extensions are part of the build:
{sp}<code>c, cpp, cc, cxx, h, hpp, mk</code>.
