This fixes the patch introduced in:
94a047ca74 (yosys: fix build on darwin, 2021-11-09)
Because we supply yosys with an external build of ABC, the patched
ABCMKARGS variable is without influence. Even if we were building with
in-tree ABC, that part of the patch is wrong, so drop it altogether.
- `toRustTarget` and friends pulled out from rust tools into rust
library. Since they don't depend on any packages they can be more
widely useable.
- `build-rust-package` gets its own directory
- `fetch-cargo-tarball` gets its own directory
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.
Followup to #76804. Fixes#144646.

Apparently this does not depend on stdenv's macOS SDK at all,
and carries around its own go-specific toolchain. So this works
fine as-is and doesn't need any changes in Nixpkgs to support a
10.13 deployment target.
This is the only collision with the default kotlin distribution and is
marked as deprecated and to be removed upstream.
```
> kotlinc
NOTE: you are running "kotlinc" CLI tool from Kotlin/Native distribution,
it runs Kotlin/Native compiler that produces native binaries from Kotlin code.
If your intention was to compile Kotlin code to JVM bytecode instead, then you
need to use "kotlinc" from the main Kotlin distribution (e.g. it can be
downloaded as kotlin-compiler-X.Y.ZZ.zip archive from
https://github.com/JetBrains/kotlin/releases/latest, or installed using various
package managers).
WARNING: if your intention was to run Kotlin/Native compiler, then please use
"kotlinc-native" CLI tool instead of "kotlinc". "kotlinc" tool will be removed
from Kotlin/Native distribution, so it will stop clashing with "kotlinc" from
the main Kotlin distribution.
```
