Why isn't MADV_FREE defined to 5 for linux? It's our first free madv

the last thing we need is slightly different behaviour from operating
systems supporting this for ages.
The behavior should indeed be identical. Both implementations
restrict MADV_FREE to work on anonymous memory and it is unspecified
whether a renewed access yields to a zerod page being created or
whether the old content is still there. So, just use 0x5 for both the
Linux and Solaris version on sparc.
