-ldl includes the reference to the library that has
the symbols for loading dynamic libraries.
So there is no need for this library for static only builds.
Even though alsa-lib uses dlopen, it has functions snd_dlopen
and others which can emulate dynamic linking for the static
build of the alsa-lib library and there is no need in libdl
dlopen when static build only.
This patch fixes build failures of the shairport-sync
(and probably other packages) when static libs are used.
Fixes:

[Thomas: use a single ALSA_LIB_CONF_OPTS for both --enable-shared=no
and --without-libdl.]
