gnupg linking against libbz2

[Okan Demirmen <okan_(_at_)_demirmen_(_dot_)_com>]

so snapshot packages, at least for i386, have gnupg linked against
libbz2, probably because the configure script found bzip2 and decided
to use it.

this patch disables bzip2 by default, but adds a flavor, if one
wishes to have that linkage.

thanks
