[Buildroot] [PATCH v2 1/4] package/sdl_sound: add optional support for libmodplug

[Bernd Kuhls]

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]
[...]
