[Buildroot] [git commit branch/next] package/gtest: needs gcc >= 4.9

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=be38432532b23275869a3a914c0ad0031323259c
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

gtest unconditionally uses is_trivially_copy_constructible since
version 1.11.0 and
https://github.com/google/googletest/commit/c13c27a513ecd1cbf5700a45fe590e85e8ae6770

So add a dependency on gcc >= 4.9 to avoid a build failure since commit
9dfbbbb4105c47602da048c9bb9499fb8862e768
