[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=e0b2041d44c32c7c6b6730137b23e4b3208ee109
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When libcap was compiled before, chrony will use it as optional
dependency:

$ output/host/usr/bin/x86_64-linux-readelf -a output/target/usr/sbin/chronyd | grep NEEDED
 0x0000000000000001 (NEEDED)             Shared library: [libm.so.1]
 0x0000000000000001 (NEEDED)             Shared library: [libcap.so.2]

 0x0000000000000001 (NEEDED)             Shared library: [libc.so.1]
