commit: https://git.buildroot.net/buildroot/commit/?id=57ace26b6c12a2602b56500e57abb2bc79e30bdc
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When libmodplug was compiled before, sdl_sound will use it as optional
dependency:

$ output/host/usr/bin/x86_64-linux-readelf -a output/target/usr/lib/libSDL_sound-1.0.so.1.0.2 | grep NEEDED | sort
 0x0000000000000001 (NEEDED)             Shared library: [libc.so.1]
 0x0000000000000001 (NEEDED)             Shared library: [libdl.so.1]
 0x0000000000000001 (NEEDED)             Shared library: [libmodplug.so.1]
