Re-enabled bytepair compression support in chkdeps. Seems it was a bug in the loader code, producing an incorrect error, that led me to disabole it originally. Commented out the apparently-incorrect check, which means theoretically some corrupt binaries won't get picked up during decompression. Which probably doesn't matter much.
