meson does not allow passing path to helper programs (e.g. pkgconfig)
using variables in the environment. Instead, it insists that those paths
be defined in the cross-compilation.conf file, in the [binaries]
section [0]
As such, allow packages to declare such a list of arbitrary entries to
add in the [binaries] section.

example, which we'll address in a follow-up patch.
