ALSA: Fix undefined symbols during static compilation

Browse Source 
These were undefined when linking with the -static flag on:

  1. Alpine Linux v3.21 x86_64
  2. Debian GNU/Linux 12 (bookworm) aarch64

In both cases I had to manually compile alsa-lib as a static library
because the systems have only .so versions. I did it with:

  cd path/to/alsa-libs
  ./gitcompile static
  <this will create alsa-libs/src/.libs/libasound.a>

Tested with alsa-libs 1.12.2 and 1.12.3.

It's possible to reproduce the errors like this:

clang -static -DMA_NO_RUNTIME_LINKING -DMA_ENABLE_ONLY_SPECIFIC_BACKENDS -DMA_ENABLE_ALSA -DMA_DEBUG_OUTPUT -Wall -Wextra -g3 simple_playback_sine.c -o build/miniwave -fcolor-diagnostics -ferror-limit=2 -fuse-ld=lld -I../
-L/home/antharas/code/alsa-lib/src/.libs/ -lasound

However, even though it compiles I can't verify that everything works.

  1. Alpine has musl which doesn't support runtime linking when
     compiling with -static. So even though I disabled it for
     miniaudio.h, libasound.a itself uses dlopen on
     libasound_module_pcm_pipewire.so.
  2. Debian uses glibc so it supports it but fails because my machine is
     a VPS that doesn't have a soundcard.

No big deal, I don't really need to statically link, it was just
something I stumbled upon.

Also these are currently unused:

  _snd_pcm_hw_params_set_rate_minmax
  ma_timer_init
  ma_timer_get_time_in_seconds
  ma_device__on_notification_rerouted
