[gentoo-dev] [PATCH 05/10] dev-lang/rust-bin: llvm-r1 and slot (-r100)

[kangie@gentoo.org]

From: Matt Jolly <kangie@gentoo.org>

Use the llvm-r1 eclass and our knowledge of the internal
LLVM used in -bin to add an appropriate `llvm_slot_{x}`
IUSE to each Rust-bin ebuild so that the Rust (and LLVM)
eclasses can select an appropriate slotted implementation.

`LLVM_OPTIONAL` is used as we don't need to consume LLVM,
we really just want the free IUSE.

Do some minor tidyup while touching _all_ of the ebuilds.
