support/config-fragments/autobuild: test Bootlin x86-64 toolchain

As we recently stopped testing the x86-64 Sourcery toolchain, it means
we no longer have any x86-64 glibc based toolchain in our
autobuilders. Since this is a pretty common configuration, it makes
sense to test it, which this commit does by adding a config fragment
to use the x86-64 glibc bleeding edge Bootlin toolchain.
