Describe the bug

scan-build program from libclang looks for ccc-analyzer in ../libexec but it is installed into a different output.

Steps To Reproduce

$ nix-build -A libclang.all
$ result/bin/scan-build -o /tmp/foo echo
scan-build: 'ccc-analyzer' does not exist at '/nix/store/54fwpd1lsgr1kadg9989cvafqkzfsqm8-clang-7.1.0/bin/ccc-analyzer'

Expected behaviour

scan-build should find ccc-analyzer.

Additional context

It works with scan-build from clang-analyzer:

$ nix-build -A clang-analyzer
$ result/bin/scan-build -o /tmp/foo echo
scan-build: Using '/nix/store/52w8z9p8m5idz4fsh9y1znmms59da8ba-clang-wrapper-13.0.0/bin/clang' for static analysis
[…]

This is bug is especially annoying because when it is first on PATH, it shadows the working program.

Possible solutions

• Remove scan-build from libclang so it has a canonical home in clang-analyzer.
• Patch scan-build code to point to lib output.
• Move ccc-analyzer to out output.
