Bug#832540: evolver: FTBFS on kFreeBSD and the Hurd: sysinfo undeclared

[Aaron M. Ucko]

Source: evolver
Version: 2.70+ds-1
Severity: important
Justification: fails to build from source

Builds of evolver for kFreeBSD and the Hurd failed:

  ../../../src/painter.c: In function 'painter_start':
  ../../../src/painter.c:441:20: error: storage size of 's' isn't known
     { struct sysinfo s;
                      ^
  ../../../src/painter.c:442:5: warning: implicit declaration of function 'sysinfo' [-Wimplicit-function-declaration]
       sysinfo(&s);
       ^

The issue appears to be that include.h's conditional inclusion of
<sys/sysinfo.h> misses these architectures.  Could you please take a look?

Thanks!
