[Aboriginal] miniconfig-busybox

[James McMechan]

I saw David Seikel's comments about still being interested in trim-config
Here is how I use mini-config with busybox, it is not hard
though I have not yet gotten the auto build stuff to include the aboriginal
tarball and the package directory in my initramfs

I was adding very little to config
 
export NO_CPLUSPLUS=1
export SYSIMAGE_TYPE=initramfs
 
My preference is for mini-config rather than trim-config so I can turn on just what I want
I am using a ~98 line mini-config which needs few changes between busybox versions
It is possible that a few more options can be turned off I would like to convert the
initramfs to bz2 and drop gzip.
Without genext2fs it appears it doesn't need TAR_OLDGNU_COMPATIBILITY
apparently that program's build environment was very very old.
