Bug#878705: opencv: FTBFS on x32: sysctl(.h) unsupported

Source: opencv
Version: 2.4.9.1+dfsg1-2
Severity: important
Tags: upstream
Justification: fails to build from source (but built successfully in the past)
User: debian-x32 at lists.debian.org
Builds of opencv for x32 (admittedly not a release architecture) have
been failing lately:
In file included from /usr/include/x86_64-linux-gnux32/sys/sysctl.h:63:0,
from /<<BUILDDIR>>/opencv-3.2.0+dfsg/modules/core/src/parallel.cpp:60:
/usr/include/x86_64-linux-gnux32/bits/sysctl.h:19:3: error: #error "sysctl system call is unsupported in x32 kernel"
Per sysctl(2), this interface is generally deprecated, so my
recommendation would be to steer clear of it on any Linux
architecture. Could you please take a look?
Thanks!
