Will Dietz 855e0463ab tree-wide: platforms = platforms.gnu; -> platforms = gnu ++ linux
"platforms.gnu" has been linux-only since at least 17.03:

$ nix eval -f channel:nixos-17.03 lib.platforms.gnu
[ "i686-linux" "x86_64-linux" "armv5tel-linux" "armv6l-linux" "armv7l-linux" "aarch64-linux" "mips64el-linux" ]

Unlike platforms.linux, platforms.gnu indicates "must use glibc"
which for the most part is not intended.

Replacing platforms.gnu with platforms.linux would be the same "today"
but let's err on preserving existing behavior and be optimistic
about platforms these packages work on.

longDescription =
'' Libchop is a set of utilities and library for data backup and
distributed storage. Its main application is chop-backup, an
encrypted backup program that supports data integrity checks,
versioning at little cost, distribution among several sites,
selective sharing of stored data, adaptive compression, and more.
The library itself, which chop-backup builds upon, implements
storage techniques such as content-based addressing, content hash
keys, Merkle trees, similarity detection, and lossless compression.
It makes it easy to combine them in different ways. The
chop-archiver and chop-block-server tools, illustrated in the
manual, provide direct access to these facilities from the command
line. It is written in C and has Guile (Scheme) bindings.
