[BRLTTY] makedev now in sysmacros.h

[Mike Gorse]

Hi,

I apologize if someone already sent a patch like this, but I don't recall 
seeing one.

Recent versions of glibc are generating a warning like this when brltty is 
compiled:

./system_linux.c: In function 'openCharacterDevice':
./system_linux.c:809:13: warning: In the GNU C Library, "makedev" is defined
  by <sys/sysmacros.h>. For historical compatibility, it is
  currently defined by <sys/types.h> as well, but we plan to
  remove this soon. To use "makedev", include <sys/sysmacros.h>
  directly. If you did not intend to use a system-defined macro
  "makedev", you should undefine it after including <sys/types.h>.
              if (mknod(path, mode, makedev(major, minor)) == -1) {

We now have the attached patch in openSUSE. sysmacros.h has existed at 
least since glibc 2.11 (ie, since 2010 or earlier), so I think that the 
patch is safe.

Thanks,
-Mike
