Removed bad make recipe dependency

[Falcon137]

I'm running OSX (15.5) and was getting this error during build:
Linking ELF file: build/us/levels/bbh/leveldata.o -> build/us/levels/bbh/leveldata.elf
mips64-elf-ld: build/us/levels/bbh/leveldata.o:(.data+0x6af4): undefined reference to spooky_09008800' mips64-elf-ld: build/us/levels/bbh/leveldata.o:(.data+0x6dfc): undefined reference to spooky_09004800'

I resolved the issue by removing a dependency in the relevant recipe. I think there is some issue with the resolution of TEXTURE_BIN when evaluating the recipe.

I don't think that second dependency is ever actually needed in the recipe header (although it is used in the build command). Whenever we build a leveldata.elf file, we are just assuming that $(TEXTURE_BIN).elf exists. If $(TEXTURE_BIN).elf doesn't exist, you'll get an error regardless of whether it is included in the recipe header.

There might be a better solution here, but this is the best I could find
