    Kbuild: use normal compression settings for tar*-pkg · b589c8ae

    For large kernel configurations (like a distribution kernel)
    targz-pkg takes a quite long time to just do the compression.
    I clocked it at 15+mins for a SUSE kernel like config on a fast
    system.  And tarxz and bzip2 are even slower.
    
    The main reason is that the script that is doing the taring sets
    the highest compression level (-9).  When I change it to just
    use the defaults the gzip time for the same kernel goes down
    to ~3 mins. I haven't tested xz and bzip, but I expect those
    to be much faster too.
    
    I'm not willing to wait that long for a small compression
    gain. So just change the script to use the defaults.
