The Makefile didn't build libbspatch and libbsdiff. This patch includes those libraries in the Makefile and moves the header files exposed by those to an include/bsdiff subdirectory following the Android convention so calling program can include "bsdiff/bspatch.h" avoiding any collision with other libraries. The Android.mk is updated to export the new include path while keeping the old style until calling programs are updated. The new Makefile allows Chromium OS to build the new libraries. Bug: None Test: FEATURES=test emerge-link bsdiff; sudo emerge bsdiff Test: mmma external/bsdiff Change-Id: I2ea9251eb224e9418fe236e4c4c9c5621853f590
