[speech_synthesis] rewrite makefile

This fixes a bunch of issues:
 - drop hardcoded x86_generic -I/-L paths for all targets
 - use standard flag namings (CXXFLAGS/CPPFLAGS/LDLIBS)
 - split compiler flags into CXXFLAGS and preprocessor flags into CPPFLAGS
 - execute pkg-config twice per *make*, not per *file compile*
 - use pkg-config for all libraries were possible (alsa/libchrome)
 - fix link order -- we need flags, then objects, then libraries
 - fix build dependencies -- make sure dirs are created before they are
   needed, and make them an order-only depend; this should allow us to
   build in parallel again rather than forcing -j1
 - drop -fPIC hardcode -- we're creating an executable, not a library
 - drop the -I.. and -Iobjs flags -- there are no headers in either place

Add a delay so that speech synthesis doesn't start up for 3 seconds.

This forces it to initialize after Chrome, and then the volume control
problems magically go away.

In measurements, it was an average of 1.1 - 1.3 seconds before Chrome
initialized audio, so a 3.0-second delay includes some cushion.
