I think lack of alsa headers leads to reduced sound functionality, not no
sound (oss gets used?).

But presumably this isn't a one size fits all problem but depends on what the
user intends to do with Emacs.  If configure just informs the user of what
functionality will be missing (rather than what libraries are missing), *he*
can decide, not us, if that is a problem or not.
