[Buildroot] [git commit] libgsasl: fix auto dependencies

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=2b4b915dd02b4c36568876350c3930ec357553d3
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

IDN can be picked up from the distro installation so use a prefix when
it's available or otherwise just disable it, fixes:
http://autobuild.buildroot.org/results/5d9/5d9baf528c47c5167ec8d2a6941cb06b4ca761ca/

Also disable libgcrypt support which wasn't accounted for and doesn't
seem to work either to possibly avoid the same problem.
