You can watch ccache being used by doing the following:
- $ watch -n1 -d prebuilt/linux-x86/ccache/ccache -s
+ $ watch -n1 -d prebuilts/misc/linux-x86/ccache/ccache -s
On OSX, you should replace `linux-x86` with `darwin-x86`.
+When using Ice Cream Sandwich (4.0.x) or older, you should replace
+`prebuilts/misc` with `prebuilt`.
