[Bug-barcode] Patch to fix build on systems without GNU libc calloc

[Clemens Lang]

Hi,

this is a follow-up to
  http://lists.gnu.org/archive/html/bug-barcode/2015-06/msg00000.html
reporting a build failure on OS X with a patch to fix the issue rather than a
workaround.

When building GNU barcode 0.99 on a system that doesn't have GNU libc calloc 
(such
as OS X), a replacement implementation is used instead. However, the sample 
binary
then fails to link because rpl_calloc is undefined. That happens because
sample_LDADD does not contain lib/libgnu.la, which would provide this symbol. 
See
the attached patch, which fixes this.

Additionally, the version number in doc/barcode.texi wasn't updated for the 0.99
release.

I have an existing copyright assignment to the FSF.
