intel: common: Fix link failure with standalone Android build

Some reshuffle in the Makefiles under src/intel resulted in Android
libraries being no longer linked with code using
src/intel/common/gen_debug.h that contains references to functions
exported by those libraries (namely ALOGW macro, which is currently
resolved into a call to __android_log_print() from cutils).

Fix the build by taking into account ANDROID_CFLAGS and ANDROID_LIBS for
affected module on Android NDK builds.

Fixes: d5b355ce5fd ("i965: Move intel_debug.h to intel/common/gen_debug.h")
