[Buildroot] [git commit] elfutils: needs wchar

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=3b595d512f52dccfa03105d83cd2a8656804cc8b
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

elfutils contains a call to wmempcpy, which is only available when the
toolchain has wchar support, so add the dependency.

Also display a comment if the toolchain dependencies are not met.
