kbuild in 2.5.51 requires that there exist one variable named obj-*
before built-in.o is generated.
In the Makefile for sound/synth/emux the variables obj-* is only set if
CONFIG_SND_SEQUENCER is set to y or m.

The best approach may be a derived bool defined in Kconfig, but
an alterneative solution is to rearrange the Makefile a bit.

Try the following (untested) patch.
