This causes parts of the audio module to be rebuilt during every incremental build, even if there are no changes: CC techpack/audio/ipc/apr.o - due to command line change CC techpack/audio/ipc/apr_v2.o - due to command line change CC techpack/audio/ipc/apr_tal_rpmsg.o - due to command line change CC techpack/audio/ipc/wcd-dsp-glink.o - due to command line change We're only experiencing this issue in techpack/audio/ipc at the moment, but kill the timestamp injection in all the audio components to eliminate the possibility of encountering this issue again in the future. This is harmless since the injected BUILD_TIMESTAMP macro is never used. Change-Id: I35b588a2a902438b2c79ebbac31453f2e528bbbe Signed-off-by: Danny Lin <danny@kdrag0n.dev>
