This won't work for a fresh clone, as the build directory wouldn't exist.
Something like this'd do:

build_dir = os.path.join(baseDir, 'build')
if not os.path.exists(build_dir):
  os.makedirs(build_dir)
(fd, name) = tempfile.mkstemp(dir=build_dir, suffix='.h')

+  buildDir = os.path.join(baseDir, 'build')
+  if not os.path.exists(buildDir):
+    os.makedirs(buildDir);
+  (fd, name) = tempfile.mkstemp(dir=buildDir, suffix='.h')
   try:
     handle = os.fdopen(fd, 'wb');
     handle.write('#include <curl/curl.h>')
     handle.close();
 
     # This command won't work for Windows or Android build environments but we
     # don't want to use curl there anyway
     command = ['/usr/bin/env', 'gcc', '-E', name];
     process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
     process.communicate()
 
     if process.returncode:
       # call failed, curl not available
       sys.stdout.write('0')
     else:
       # call succeeded, curl can be used
       sys.stdout.write('1')
   finally:
     os.remove(name)
 
 if __name__ == '__main__':
   check_curl()
