The aws-sdk-cpp tests are flaky.
Since pull requests to staging cause nix to be rebuilt, this means
that staging PRs end up getting false CI failures due to whatever is
flaky in the AWS SDK tests. Since none of our CI needs to (or
should be able to) contact AWS S3, let's just omit it all. Bonus:
the tests build way faster.
We have several cross-compilation bugs that show up if
hostPlatform!=buildPlatform yet
hostPlatform.config==buildPlatform.config.
These bugs have appeared and disappeared as we've fiddled with the
definition of equality for platform objects. This commit adds a
clear-cut case where they are *not* equal and never will be, so we
can test it.
This does decrease performance unfortunately

Currently just throws the Nix error because unknown file types are not
supported by the Nix store, but nothing catches this error earlier (yet,
see next commit)
gnu-config will ignore the portion of a triple matching the regex
`e?abi.*$` when determining the validity of a triple. In other
words, `i386-linuxabichickenlips` is a valid triple.
This commit updates our parsing routines to match gnu-config.
I was recently surprised to discover that it is in fact possible to
shoehorn ABI flavors into nix doubles in a way which preserves their
property of being a (non-canonical) subset of the valid gnu-config
triples. This commit is required in order to exploit that discovery
to add automatic detection of ILP32 platforms (64-bit void*, 32-bit
int, like the Apple Watch and MIPS n32) to Nix.
Add the "Type:" blocks.
Move the examples below the descriptions whenever possibles
Add "Example:" tags before the examples moved below the descriptions.
For transforming back between lists and attrsets, it makes sense to have
a quasi-inverse of `builtins.listToAttrs` available as a library
function.
