You are mistaken. I've succuessfully just built one sound driver +
the pcm base with using
makeoptions MODULES_OVERRIDE="sound/pcm sound/driver/es137x"

the patches rather than a failing in the patches.
Note, I had to patch the Makefile.${MACHINE_ARCH} as well, so the
complete patch looks more like:
