alg: comp: Compression test 1 failed for lz4

[Christian Kujau]

Hi,

while the LZ4 and LZ4HC module appears to be available on PowerPC 32-bit 
(it's a PowerBook G4), I get these warnings below during module load. The 
lzo module is working just fine and I'm using it extensively for ZRAM on 
that machine.

Is this a configuration[0] error or is LZ4 just not supported for this 
architecture?

Thanks,
Christian.

    I get the same messages with a stock Debian/4.9 configuration too.
