Chris Metcalf d90a2d26c1 tile: remove MAP_CACHE_xxx support in mem.c 
These flags support functionality in mmap() that has not been
pushed back to the community, and which may or may not eventually
end up being the final community model.  In the interim, having
these flags unconditionally present for "#ifdef TILE" just means
that the TILE build breaks if using the community versions of
the kernel and glibc, so just revert the code until such time
as it may end up in the community.

* XXX - this was introduced in SunOS 4.x to distinguish between

*
* only let you map devices with an "mmap" routine (e.g.,
* frame buffers) in;
*
* required you to specify the mapping address;
*
* returned 0 on success and -1 on failure;
*
* memory and which, and the 4.x "mmap()" which:
*
* can map plain files;
*
* can be asked to pick where to map the file;
*
* returns the address where it mapped the file on success
* and -1 on failure.
*
* It's not actually used in source code that calls "mmap()"; the
* "mmap()" routine adds it for you.
*
* It'd be nice to come up with some way of eliminating it from
* the flags, e.g. reporting calls *without* it as "old_mmap()"
* and calls with it as "mmap()".
