liblivemedia fails to cross build from source, because it builds for the
build architecture. debhelper sees the presence of a configure script
and treats it as an autoconf project expecting that configure records
cross compilers, but this configure script configures nothing.
liblivemedia needs to be built like a makefile project. Requesting this
explicitly makes dh_auto_build pass cross tools to make and that is
enough to make liblivemedia cross buildable. Please consider applying
the attached patch.
