Ah, but finally, I'm not sure it should be added here.  Do we have a better
place common for all Android-related things?  (e.g. base/base.gyp for Linux)

this is exactly the same as the block below :)
each target decides whether or not to link against allocator. I collapsed into a
single condition below.

         ['os_posix==1 and use_aura==1 and linux_use_tcmalloc==1', {
           'dependencies': [
             # This is needed by content/app/content_main_runner.cc
             '../base/allocator/allocator.gyp:allocator',
           ],
