[Buildroot] [PATCH 2/2] package/links: add optional support for xz

[Bernd Kuhls]

When xz was compiled before, links will use it as optional dependency:

$ output/host/usr/bin/i586-buildroot-linux-uclibc-readelf -a output/target/usr/bin/links | grep NEEDED
 0x00000001 (NEEDED)                     Shared library: [liblzma.so.5]
 0x00000001 (NEEDED)                     Shared library: [libbz2.so.1.0]
 0x00000001 (NEEDED)                     Shared library: [libz.so.1]
 0x00000001 (NEEDED)                     Shared library: [libevent-2.0.so.5]
 0x00000001 (NEEDED)                     Shared library: [libc.so.1]
