With the default kernel and thus with the build I have tested in
74ec94bfa2, we get an error during
modules_install:
make[2]: execvp: /nix/store/.../bin/bash: Argument list too long
I haven't noticed this build until I actually tried booting using this
kernel because make didn't fail here.
The reason this happens within Nix and probably didn't yet surface in
other distros is that programs only have a limited amount of memory
available for storing the environment and the arguments.
Environment variables however are quite common on Nix and thus we
stumble on problems like this way earlier - in this case Linux 4.8 - but
I have noticed this in 4.7-next as well already.
The fix is far from perfect and suffers performance overhead because we
now run grep for every *.mod file instead of passing all *.mod files
into one single invocation of grep.
But comparing the performance overhead (around 1s on my machine) with
the overall build time of the kernel I think the overhead really is
neglicible.

The postPatch attribute is already in the function argument but is
unused elsewhere in the code, so setting postPatch with buildRebar3 is
going to end up in a no-op.
This now allows to use postPatch within buildRebar3 by simply appending
to the existing postPatch hook that removes the rebar and rebar3
escripts.

For some reason `gem install` unsets the GEM_PATH environment variable
internally unless the install dir is provided. This in turn means that
if it invokes extconf.rb and extconf.rb depends on a gem available on
the GEM_PATH (like pkg-config for nokogiri) then it's not available in
that context.

This is a hack that sets the :install_dir to where we would install
anyways (the GEM_HOME is the default installation destination).
Tested by only building the linux_testing attribute, but haven't yet
tested it in production.
I've also fixed the extraMeta.branch attribute.
