package/binutils: add optional support for zlib
When zlib was compiled before, binutils will use it as optional dependency: $ output/host/usr/bin/x86_64-linux-readelf -a output/target/usr/lib/libbfd-2.24.so | grep NEEDED 0x0000000000000001 (NEEDED) Shared library: [libz.so.1] 0x0000000000000001 (NEEDED) Shared library: [libc.so.1] Apparantly the build system offers no support to control the dependency, --without-system-zlib with zlib installed still provides libbfd-2.24.so linked to libz.so.1.
