[Pkg-libvirt-maintainers] Bug#843794: [libvirt] tweak build dependencies to allow building for jessie

[fld]

Package: libvirt
Version: 2.4.0-1
Severity: wishlist

--- Please enter the report below this line. ---
Currently, on Debian jessie the build process depends on resolving:
Backporting package libvirt in sid→jessie/amd64: unsatisfiable build dependencies: Build-Depends libxml2-dev (>2.9.2+really2.9.1+dfsg1-0.2).

But, using "dpkg-buildpackage -d -b -uc", the build does succeed on jessie 
even with libxml2-dev (2.9.1+dfsg1-5+deb8u3) installed.

Could the B-D be relaxed to allow building on jessie without having to use -d?
