I recently added the same thing to naclports:
https://chromium.googlesource.com/external/naclports/+/d814530ee8217cb91bb4c6...

Can you take the macros from there?  (The versions I
included are from newlib/libc/sys/linux/sys/param.h)

Can you also mention this change in README.chromium in
the newlib-extras folder?

otherwise lgtm.
