Oops! '$ make allmodconfig' seems to enables all compression algorithms;
So the last one overrides the previous choices in usr/Makefile.
Please see an updated patch herein. I've patched 'gen_initramfs_list.sh'
script to check if a selected compression command is accessible or not;
And fall-back to the default gzip(1) format when it is not. usr/Makefile
also defaults to '.gz' format when all are enabled.
