Bug#637695: memcached: Fix FTBFS on hurd-i386

[Svante Signell <svante.signell@telia.com>]

Package: memcached
Version: 1.4.5-1
Severity: important
Tags: patch
User: debian-hurd@lists.debian.org
Usertags: hurd

The attached patch fixes the FTBFS problem for GNU/HUrd, and at the
same time makes the PATH_MAX definition redundant for all
architectures. Connected with the patch for bug #625397 memcached
builds perfectly on GNU/Hurd with gcc-4.6.

Thanks
