`SSL_CERT_FILE` has been replaced with `NIX_SSL_CERT_FILE`.
Before this change using `fetchdarcs` resulted in an error message like:
```

HINT: Do you have the right URI for the repository?

I was getting the following error building tide from Melpa:

Solution was to disable the large file warning threshold when
installing packages.
This still causes some uncached rebuilds, but master(!) and staging
move too fast forward rebuild-wise, so Hydra might never catch up.
(There are also other occasional problems.)
Therefore I merge at this point where the rebuild isn't that bad.
We need to make sure that `$revs` ends with a space, since files must always
end with newlines. The previous code ignored the last entry in `$revs`, because
read already returns non-zero exit code for the last entry, as it does not end
with a space.
This change fixes several defects in the way `wrapGAppsHook` selected
the executable to wrap.
Previously, it would wrap any top-level files in the target `/bin` and
`/libexec` directories, including directories and non-executable
files. In addition, it failed to wrap files in subdirectories.
Now, it uses `find` to iterate over these directory hierarchies,
selecting only executable files for wrapping.

When not using sandboxing, /usr/share/git-core/templates may leak into the
nix build through the libgit2 hardcoded default template search path. We now
explictly set the templatedir to avoid this problem.
See https://github.com/bennofs/nix-index/issues/2#issuecomment-296268983 for
an example case of nondeterminism.
This typo was likely introduced by copy-pasting the error message from elsewhere and forgetting to change the text, during the MD5 deprecation process (#4491).
This patch fixes file modification times to $SOURCE_DATE_EPOCH, and
ensures that files originating from the store are owned by root:root.
Both changes improve reproducibility, and the latter allows proper
building on a host where the store is owned by a non-root user.
