What you actually want here is to use architecture wildcards, as in:
libasound2-dev [linux-any]
this is documented in dpkg-architecture(1), and has been supported since
dpkg 1.13.13. debhelper also supports this since 5.0.36. Currently the
only missing piece I'm aware of is sbuild, but next upload to Debian
should support it (#501230). It'd be really nice to get that patch on
the buildds so that we could start using this in the archive.
