Subject: rpm helpers: add support for gbp-specific rpmlib
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=89e46dfeffe73f0dba33f708e94f726d6b3991ec;p=tools%2Fgit-buildpackage.git

rpm helpers: add support for gbp-specific rpmlib

Adds support to use a special rpmlib, defined by rpm packaging policy.
This makes it possible to use the target distro's rpmlib. That is, parse
spec files for target distros (and architectures) incompatible with your
host system.

With the default RpmPkgPolicy, GBP tries to import "rpmlibgbp".
