Hello dietlibc members:
When I sent a Linux kernel patch for uapi, some members suggest me to
Cc dietlibc members, so I forward the related mail to dietlibc mailing
list.
Please check, and welcome any ideas, suggestions, or completions.
Thanks.

For uapi, need try to let all macros have same value, and MADV_FREE is
added into main branch recently, so need redefine MADV_FREE for it.
At present, '8' can be shared with all architectures, so redefine it to
'8'.
