This cross compiler from ARM is a bare metal compiler, so it cannot build Linux userspace applications/libraries. Therefore, trying to use this compiler with Buildroot does not make much sense, because the whole point of Buildroot is to build a Linux system, with Linux userspace applications and libraries.
