Weirdness.

So I've copied i386/cputest.c to cpu-test.c and modified the relevant
line in libavcodec/Makefile to

$(SUBDIR)cpu-test$(EXESUF): $(SUBDIR)cpu-test.o $(SUBDIR)$(LIBNAME)
$(SUBDIR)fft-test$(EXESUF): $(SUBDIR)fft-test.o $(SUBDIR)$(LIBNAME)

which is an exact analog of fft-test.  fft-test builds fine, cpu-test
does not get built...
