[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=018843ce1bfe1c83d12a3e12f9b9b4c986ec9e7d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When libexif was compiled before, libfm will use it as optional
dependency:

$ output/host/usr/bin/x86_64-linux-readelf -a output/target/usr/lib/libfm.so.4.0.3 | grep NEEDED | sort
 0x0000000000000001 (NEEDED)             Shared library: [libc.so.1]
 0x0000000000000001 (NEEDED)             Shared library: [libdl.so.1]
 0x0000000000000001 (NEEDED)             Shared library: [libexif.so.12]
[...]
