[Buildroot] [git commit] alsa-lib: fix build on bfin

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=9a6d3456f3e7965f30648fd09ef54b13109d210d
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Bfin toolchains don't have versionsort (which alsa-lib needs), so fake it
using alphasort instead.

Fixes http://autobuild.buildroot.net/results/cf760651b2e238842813bf0882011b5fbb898c0d
