support/config-fragments/autobuild: use Bootlin toolchain for ARMv7 glibc

Instead of using an external toolchain built specifically for the
autobuilders to test ARM Cortex-A9/glibc, use a pre-built Bootlin
toolchain. Since this was meant to test very recent version of
toolchain components, we use the bleeding edge toolchain variant.
