What kernel are you using? and where is your /usr/src/linux symlink pointing to? what compiler? What USE flags? what CFLAGS? details details details Personally looks to me like a bad /usr/src/linux symlink or wrong configed kernel or incompatible kernel version.
I'm closing this bug because that's exactly what the problem is. Your /usr/src/linux symlink is not pointing to your current kernel sources.
