Problem is that in the example above, Thomas was keying on the gcc
version, or the glibc version. But maybe at some point it's not the gcc
version or glibc version that changed, but the fact that they switched
for EABI to EABIhf.

config BR2_TOOLCHAIN_EXTERNAL_LINARO_VARIANT_1
config BR2_TOOLCHAIN_EXTERNAL_LINARO_VARIANT_2
config BR2_TOOLCHAIN_EXTERNAL_LINARO_VARIANT_3
