Teach cc_configure about BAZEL_LINKLIBS env variable

Using this variable is will be possible to specify system libraries that
should be added after default linker flags, after libraries to link, and
after user link flags (i.e. after --linkopt and `linkopts` rule attribute).

Flag separator is `:`, similarly to `BAZEL_LINKOPTS`. Escaping is done by
`%`.

Default value is empty string.

With this it's possible to force Bazel to statically link `libstdc++` by
using:

```
BAZEL_LINKOPTS=-static-libstdc++ BAZEL_LINKLIBS=-l%:libstdc++.a bazel build //foo
```

Fixes https://github.com/bazelbuild/bazel/issues/2840.
Relevant for https://github.com/bazelbuild/bazel/issues/8652.

RELNOTES: Bazel's C++ autoconfiguration now understands `BAZEL_LINKLIBS` environment variable to specify system libraries that should be appended to the link command line.

Closes #8660.

Bazel

{Fast, Correct} - Choose two

Build and test software of any size, quickly and reliably.

  • Speed up your builds and tests: Bazel only rebuilds what is necessary. With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds.

  • One tool, multiple languages: Build and test Java, C++, Android, iOS, Go, and a wide variety of other language platforms. Bazel runs on Windows, macOS, and Linux.

  • Scalable: Bazel helps you scale your organization, codebase, and continuous integration solution. It handles codebases of any size, in multiple repositories or a huge monorepo.

  • Extensible to your needs: Easily add support for new languages and platforms with Bazel's familiar extension language. Share and re-use language rules written by the growing Bazel community.
