[Buildroot] [git commit] package/links: add optional support for libevent

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=ec1c53afd33b590200a4503dab16cce41864fabb
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When libevent 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]

(xz support will be added with the next patch of this series)
