[alsa-devel] [PATCH 7/8] Avoid including sys/io.h on architectures that lack it.

[Jordi Mallach]

Extend the check for PowerPC to the rest of official and unofficial
Debian linux-based architectures that lack sys/io.h, based on EGLIBC 2.17.
sys/io.h is available, at the time of this writing, on the alpha, i386,
ia64, and arm Linux targets.
