[libc-commits] [libc] [libc] express proper dependencies for stdbit include test (PR #80318)

[Nick Desaulniers via libc-commits]

https://github.com/nickdesaulniers created https://github.com/llvm/llvm-project/pull/80318

If the entrypoints aren't available for a target, don't run the include test.

We should add these entrypoints to more targets, but in addition I should stop
breaking the build when I add more functions to this include test.
