"linux-generic" and "tile" support committed to libc-ports

[Chris Metcalf]

I just pushed the "ports" support for linux-generic and tile up to the git
repository; it's in these directories:

  sysdeps/unix/sysv/linux/generic
  sysdeps/tile
  sysdeps/unix/sysv/linux/tile

Earlier this evening I mailed out the remaining patches that are needed
from the core libc so it will build for tile.  They are:

- elf/elf.h to support tile
- hidden symbol for epoll_pwait() to avoid PLT
- __NR_openat support in not-cancel.h
- bugfix in scripts/firstversions.awk

Since we build with -Os at Tilera, it would be nice if the proposed patch
for faccessat() were taken as well.

In addition, config.guess/config.sub need to be synced up from gnulib
(2011-06-03 or newer).

Many thanks to those who have worked with me to get the code suitable for
committing, particularly Joseph Myers and Roland McGrath.
