Version: 1.0.5-4

lv2-c++-tools fails to cross build from source, because it builds for
the build architecture. It has a ./configure script, but it doesn't
actually set up cross tools as debhelper expects. Thus when debhelper
runs make, it doesn't pass cross tools along. From a debhelper
perspective, this is more of a makefile build system than an autoconf
build system. Once we tell it, it passes cross tools.

Those are mostly picked up by the build system except for pkg-config. It
needs a little patch to honour the variables passed by dh_auto_build.

Please consider applying the attached patch.
