Bug#552043: pam: FTBFS on hurd-i386: PATH_MAX usage in test application

[Pino Toscano]

Package: pam
Version: 1.1.0-4
Severity: important
Tags: patch
User: debian-h...@lists.debian.org
Usertags: hurd

Hi,

pam fails to build on GNU/Hurd because of a single test application
unconditionally using PATH_MAX.
The attached patch (hopefully trivial enough) fixes the problem and makes pam
buildable, including all successful test cases.

Thanks,
