[libc]: fix missing linux/error-number-macros.h (#97101)

izaakschroeder · web-flow · commit 74852bfa4cfd · 2024-06-28T14:55:25.000-05:00
The headers installation previously missed platform-specific number macros, and this fixes that. From discussion on LLVM discord with `michaelrj` – ccing @michaelrj-google who hopefully is the same person 😅 N.B. I have tested this manually in my Linux Dockerfile and it appears to do the right thing; I haven't done much more than that.
