This configuration works just fine for me:

BR2_arm=y
BR2_cortex_a9=y
BR2_ARM_ENABLE_VFP=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM=y
BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y
BR2_TOOLCHAIN_EXTERNAL_URL="https://releases.linaro.org/components/toolchain/binaries/5.4-2017.01/arm-linux-gnueabihf/gcc-linaro-5.4.1-2017.01-x86_64_arm-linux-gnueabihf.tar.xz"
BR2_TOOLCHAIN_EXTERNAL_CUSTOM_PREFIX="arm-linux-gnueabihf"
BR2_TOOLCHAIN_EXTERNAL_GCC_5=y
BR2_TOOLCHAIN_EXTERNAL_HEADERS_4_0=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM_GLIBC=y
BR2_TOOLCHAIN_EXTERNAL_CXX=y

But well, you really don't need to configure this toolchain manually,
Buildroot already supports the Linaro toolchain by default, just select
it in the list of external toolchains.

Best regards,

Thomas
