It's not clear to me what this is achieving, plus for some reason this
is causing an evaluation error in hyperterm. So let's hope it's not
really needed...

The -rc kernels are quite likely to break out-of-tree modules and thus
cause unnecessary Hydra failures.
(Note that linux_testing already has `hydraPlatforms = [];` but that
does not prevent the package from being built since it has reverse
dependencies. Arguably that could be considered undesirable and thus
fixing that could be considered the proper fix, but this should do
for now.)
This one was already merged into release-16.09, so let's not have the
stable branch is ahead of master and confuse things. In addition to
that, currently we have an odd situation that master has less things
actually finished building than in staging.

These are now showing up as broken builds in Hydra since 2daefaf457.
None of these compiled even in 16.03 and I think all of them are
for pretty obsolete hardware, so just mark them as broken.
(In principle the xorg generator could be made to ignore them but that
would be more work.)

This doesn't change the resulting x86 configs, but is more useful for
other architectures. For instance, POSIX_MQUEUE is currently missing
on ARM.
