Attachment: Bug 1430087 - Build sccache with system GCC/binutils.

It was failing to build with the GCC/binutils on the CentOS-based docker
image, but it doesn't with the Debian-based one, so we can remove the
dependency on the gcc toolchain task. This allows sccache to remain
untouched when we change the gcc build scripts, and more importantly,
this allows it to depend on no toolchain that requires building things.

This makes it now possible to use sccache as a dependency for all other
toolchains jobs that compile, if that's beneficial (which might not be
the case, given the current sccache retention time, but at least it's a
viable option, now)

Does this mean we're OK with building the openssl required here with whatever random `cc` is available?

I know we discussed this at some point but I can't remember what we decided. Using sccache for other toolchain jobs should at least help make the "dozens of toolchain jobs pile up when a toolchain change lands" situation better, since tasks that are started while a task is still running on a previous push ought to be able to get cache hits. We could also create a separate s3 bucket for toolchain use with a longer expiration date, or add s3 prefix support to sccache and put a prefix in the existing sccache buckets for toolchain use with a longer expiration date.

Why shouldn't we (it's GCC 4.7, fwiw)
