In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

Naive concatenation of $LD_LIBRARY_PATH can result in an empty
colon-delimited segment; this tells glibc to load libraries from the
current directory, which is definitely wrong, and may be a security
vulnerability if the current directory is untrusted. (See #67234, for
example.) Fix this throughout the tree.

This commit adds mltonHEAD.
Summary of all the changes in this branch:
* mlton20130715
- for this one I just copy and pasted the old default.nix
- I have tested some projects that compile with this version and don't
compile with the newer version, so I think it makes sense to keep
the old version
* mlton20180207Binary
- This is used to build the source derivations
* mlton20180207
- latest release
* mltonHEAD
- latest commit to the master branch of the github repo at the time of
creating this derivation
This works the same as the binary package in the old derivation, by
patching the release binary. The difference is that this derivation
is also exposed at the top level.
In a few cases it wasn't clear so I left them as-is.
While visiting these moved other things to nativeBuildInputs
when it was clear they were one of these cases:
* makeWrapper
* archive utilities (in order to unpack src)
* a few of these might no longer be needed but leaving for another day
Allow mlton to compile in a more barren sandbox. The bootstrapping
binaries for darwin have dynamic linking dependencies outside of the nix
store. This patch shifts them to point to the appropriate library within
the nix store.
* Remove package name
* Start with upper case letter
* Remove trailing period
Also reword some descriptions and move some long descriptions to
longDescription.
I'm not touching generated packages.
