Bug#926347: suitesparse: FTBFS on hurd-i386: mach/clock.h non-existent on GNU/Hurd

[Paul Sonnenschein]

Package: suitesparse
Severity: normal
Version: 1:5.4.0+dfsg-1
Tags: patch
User: debian-hurd at lists.debian.org
Usertags: hurd
X-Debbugs-CC: debian-hurd at lists.debian.org

Suitesparse fails to build from source on hurd-i386 because the header
mach/clock.h is not contained in GNU Mach, however it gets included in
GraphBLAS/Demo/Include/simple_timer.h used by
GraphBLAS/Demo/Source/simple_timer.c.

For a detailed log, please see [0].

The patch consists of the following changes:

simple_timer.h
 1. Enable the Linux case (not strictly necessary, due to the existence
    of an OpenMP and a C11 fallback case).
 2. Enable the Mach case only if __APPLE__ is defined

simple_timer.c
 1. Enable the Linux case on Hurd (not necessary, see simple_timer.h)
 2. Disable the Mach case unless __APPLE__ is defined (not strictly
    necessary, because of the OpenMP case)

Using the Linux case is recommended in [1], however [1] does not
mention the C11 clock function.

Thanks,
	Paul Sonnenschein
