Linux's PHP runtime binary

[GoogleCodeExporter]

What steps will reproduce the problem?
When attempting to locally launch a PHP runtime environment using a Linux 
machine devappserver2.py fails to find Linux's PHP runtime binary.

What is the expected output? What do you see instead?
Upon launch, we expect the binary to be identified and the local instance 
started. Instead we see the following:

>>> gcloud preview app run .
Module [default] found in file [app.yaml]
INFO: Skipping SDK update check.
INFO: Starting API server at: http://localhost:57753
INFO: Starting module "default" running at: http://localhost:8080
ERROR: The PHP runtime is not available

What is the output of 'gcloud info'?

Please provide any additional information below.

devappserver2.py looks for the PHP binary with the _get_default_php_path() 
function. If statements against python's sys.platform output is only validating 
'darwin' and 'win32'. For linux support, I was able to add 'linux2' to the 
'darwin' elif statement (maybe use a str.match for 'linux' to support the 
various distributions?). 

From Linux Mint 17:
>>> import sys
>>> print sys.platform
linux2

platform/google_appengine/google/appengine/tools/devappserver2/devappserver2.py

  elif sys.platform in ('darwin', 'linux2'):
    base_paths = [os.path.realpath(sys.argv[0]), sys.argv[0]]
    for base_path in base_paths:
      default_php_executable_path = os.path.abspath(
          os.path.join(os.path.dirname(os.path.dirname(base_path)), 'php-cgi'))
      if os.path.exists(default_php_executable_path):
        break
      elif os.path.exists('/usr/bin/php-cgi'):
        default_php_executable_path ='/usr/bin/php-cgi'
        break

We do not ship a PHP binary with the Cloud SDK on linux (you need to build / 
install one manually).  Once you do this, you can simply use the 
--php-executable-path on `gcloud preview app run` to point to the location of 
the php binary.
