support/config-fragments/autobuild/br-arm-internal-glibc: update to bleeding edge components

The br-arm-internal-glibc.config is generally used as a configuration
to test the bleeding edge versions of components. However, it has been
lagging behind somewhat, so let's bring it up-to-date:

 - Binutils 2.36.x
 - GCC 11.x

Let the fun begin in the autobuilders!
