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'.

Hmmm... you might want to talk to the dietlibc people if you do this:

$ grep -rn MADV_FREE /usr/include/
/usr/include/diet/sys/mman.h:101:#define MADV_FREE      0x5             /* (Solaris) contents can be freed */

Though the sole definition only exists on sparc/powerpc/powerpc64, so who
knows...

Excuse me, I am not quite familiar about dietlibc. If possible, please
help forward this mail to them, and Cc me (if necessary).

Thanks.
