gnu: cross-binutils: Build with `--with-sysroot'.
This fixes resolution of DT_NEEDED entries in cross-built libraries. For instance, if ltdl.so needs libdl.so and has it in its RUNPATH, then libdl.so is searched for in the right place. * gnu/packages/cross-base.scm (cross-binutils): Pass `--with-sysroot=/no-such-path'.
