Sergei Trofimovich a74147fe6a stdenv/linux: disable and drop isl from gcc's bootstrap tools
`isl` is only needed to support `gcc` transformations enabled by
`-fgraphite*` options. Packages do not usually use those flags. None of
the bootstrap packages use it.

`nixpkgs` does not use up-to-date `isl` for `gcc` either. Let's drop
`isl` dependency from the bootstrap binary seed.
