Bug#955351: mesa: FTBFS on hurd-i386

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

Source: mesa
Version: 20.0.2-1
Severity: important
Tags: ftbfs, patch
User: debian-hurd@lists.debian.org
Usertags: hurd

Hello,

Currently mesa FTBFS on GNU/Hurd due to a new PATH_MAX issue. Version 
18.3.6-2 built successfully earlier. The attached patch path_max.diff
fixes that problem. Also, the symbols file for libglx-mesa0 is
mismatched, and an architecture-specific file for Hurd, libglx-
mesa0.symbols.hurd, is attached.

Thanks!
