Buildroot toolchain,

BR2_x86_64=y
BR2_TOOLCHAIN=y
BR2_TOOLCHAIN_USES_GLIBC=y
BR2_TOOLCHAIN_BUILDROOT=y
BR2_BINUTILS_VERSION_2_35_X=y
BR2_GCC_VERSION_10_X=y
BR2_PACKAGE_BATMAN_ADV=y

Yes, deleted the build/batman-adv* dir and fully re-built, and
confirmed that it was not setting the BATMAN_ADV_V flag anymore.

Thanks,
Christian
