Don't we already have the ability to disable individual audio backends ?
Each of them relies on a different 3rd party library that we have to
check for, with none of them being mandatory. 

I feel like we shouldn't have a "--disable-audio" at all. For backends
we always go for having ways to disable individual dependencies, and
for frontends we provide Kconfig for fine tuning what's enabled for
a given target.
