This patch allows the Window sdk build (lunch sdk-eng; make win_sdk) to work properly when USE_CCACHE is defined in the environment. There is no Windows ccache prebuilt, but since we're cross-compiling from Linux, detect it and use the linux prebuilt binary instead. Note: Depends on https://review.source.android.com//#change,21755 for a complete solution to the problem. Change-Id: I0b1b59efae86ee7114225258c9ecf9f257913347
