GYP changes and scripts for compiling Skia for ChromeOS

-# This GYP file stores the dependencies necessary to build Skia on the Android
+# This GYP file stores the dependencies necessary to build Skia on the Chrome OS
 # platform. The OS doesn't provide many stable libraries as part of the
 # distribution so we have to build a few of them ourselves.
-#
-# NOTE: We tried adding the gyp file to the android/ directory at the root of
-# the Skia repo, but that resulted in the generated makefiles being created
-# outside of the out directory. We may be able to move the bulk of this gyp
-# to the /android directory and put a simple shim here, but that has yet to be
-# tested.

how this is compiling on Linux?

This file is only related to ChromeOS.  For that standard linux build see
trunk/gyp/images.gyp and you will find that on linux we expect the host OS to
have installed gifn development libs and we just link using -lgif.
