Bug#1005958: nvidia-settings FTCBFS: missing cross tools ld and objdump

[Helmut Grohne]

Source: nvidia-settings
Version: 510.47.03-1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

nvidia-settings fails to cross build from source, because it uses the
build architecture variants of ld and binutils to convert png images to
ELF objects. It later fails linking them. The build system expects the
standard variables that dpkg's buildtools.mk sets, but dh_auto_build
only passes a safe subset explicitly. Enabling all of them makes the
build proceed here. Unfortunately, it later runs host code to generate
its manual pages. That's a harder problem to solve. The attached patch
only covers the former. Please consider applying it anyway and close
this bug when doing so.
