Subject: [PATCH] python3Packages.lxml: fix cross-compilation

Rather than relying on lxml's build system to find its dependencies by path, use
the pkg-config hook.  This makes cross-compilation work, as otherwise the build
will attempt to link build platform libs while making host platform outputs.
