Since tile support has been removed from the Linux kernel for 4.17,
this patch removes the (unmaintained) port to tilegx from glibc (the
tilepro support having been previously removed). This reflects the
general principle that a glibc port needs upstream support for the
architecture in all the components it build-depends on (so binutils,
GCC and the Linux kernel, for the normal case of a port supporting
the
Linux kernel but no other OS), in order to be maintainable.
Apart from removal of sysdeps/tile and sysdeps/unix/sysv/linux/tile
(omitted from the diffs below), there are updates to various comments
referencing tile for which removal of those references seemed
appropriate. The configuration is removed from README and from
build-many-glibcs.py. contrib.texi keeps mention of removed
contributions, but I updated Chris Metcalf's entry to reflect that he
also contributed the non-removed support for the generic Linux kernel
syscall interface. __ASSUME_FADVISE64_64_NO_ALIGN support is
removed,
as it was only used by tile.
Given tilegx/tilepro removal from the kernel and glibc, should we go
ahead and deprecate them in GCC? The only tilegx/tilepro
configurations
are -linux.
Makes sense to me. Let's deprecate it for GCC 8 and remove from trunk.

Here's what I committed to the trunk and the release branch. I'll
find/update the appropriate web page momentarily.
It's been deprecated since GCC 8 now but the port is still on trunk,
guarded by --enable-obsolete - is it time to remove it?
Definitely. Folks have had years to complain.
If you wanted to add cr16 to the deprecated ports list, I'd fully
support that as well. It hasn't built since dropping cc0 and there
doesn't appear to be anyone interested in making it work.
