Thanks for the contribution, there are some adjustments that I would 
suggest making to more maintainable.

You should be using PACKAGECONFIG here instead of base_contains.

Also, you can use ALLOW_EMPTY_libasound-module-bluez = "1" so that it 
does not matter if the files are available

The base_contains is not needed here, if the alsa-lib/*.la files are not 
there then I don't think any warnings or errors will occur
