patch already committed to patches-blfs

add gdbm as optional

Bruce, as I wrote yesterday in dev, I added a patch for this. Knew that an sed could be used. instead. Took me a while (always does, to me) to find out how to add new lines, to match exactly the patch, here it is:

sed -e '/attr.mdh/ d' -e '/attr.pro/ d' \
    -e '/include <sys\/xattr.h>/ a\\n#include "attr.mdh"\n#include "attr.pro"' \
    -i Src/Modules/attr.c

I am telling that here, because I had already fixed "qemu-1.7.0 won't build with libcap-2.24", in ticket #4553, created by Wayne, so we can remember, because it is possible that it will be needed elsewhere, again.

Edited the sed, to remove unneeded space.

Fixed at r12764.
