    Remove tilegx port. · a3fb6b6b
    Joseph Myers authored
    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,
    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.
