Bug#745485: xdebug: FTBFS on hurd-i386

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

Source: xdebug
Version: 2.2.4-1
Severity: important
Tags: patch

Usertags: hurd

Hi,

Currently xdebug fails to build from source due to PATH_MAX being used,
and that constant is not defined on GNU/Hurd. The attached patch avoid
using PATH_MAX by allocating the string dfp with xdstrdup() and free it
when not needed any longer.

Thanks!
