[PATCH v2 7/10] Tilera (and Linux asm-generic) support for glibc

[Chris Metcalf]

(Unchanged since v1 of the patch)

2011-11-03  Chris Metcalf  <cmetcalf@tilera.com>

  * include/unistd.h (__readlink): Use the correct return type
  for __readlink() to match readlink().  Required for generic Linux
  ABI port, which implements __readlink() as C code.
