[Buildroot] [git commit] ola: Bump to 0.9.4

[Buildroot] [git commit] ola: Bump to 0.9.4

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=64dd1e50f84a82c5dcc31cb376463bce48d80b5d
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The protoc stuff changed a bit since 0.9.3. When 0.9.4 was released,
support for cross-compiling was broken because of it. A patch was merged
upstream shortly after that fixes the problem, so I included it here.
When the next version is released, the patch should not be necessary
anymore.

[Peter: actually change _VERSION]

+Subject: [PATCH] Fix finding ola_protoc_plugin when cross-compiling
+
+It seems like the recent changes concerning ola_protoc did not take into
+account cross-compiling.
