[libc-commits] [libc] [libc] Fix installed 'math.h' header paths (PR #83199)

[via libc-commits]

https://github.com/lntue commented:

I think we plan (and currently we do) to directly include many of those headers in `llvm-libc-macros` and `llvm-libc-types` directly in our internal implementations inside `src` folder, we should add `libc/include` in the include paths so that internal inclusions will match with installed headers as `#include <llvm-libc-macros/*>`.  WDYT? @nickdesaulniers @michaelrj-google @gchatelet
