Please keep in mind, that usr/include/ currently does not hold a single
header file but is used for dynamically composing the UAPI header tree.

In general, I do not like the idea of keeping a elf.h file here that
possibly is out-of-sync with the actual system's version (even though
elf.h should not see that much changes).  Might it be more helpful to
provide a "development kit" for Linux devs that need to build on MacOS
that provides necessary missing system header files, instead of merging
those into upstream?

Kind regards,
Nicolas
