This reverts commit 7fc57a998aa441f62884a0593456b9d5c0eb00c5.
Add kernel config for i486
Fix mpg123 to compile with our i486 toolchain
Update README
kernel_headers depends on crossmusl
9base depends on kernel_headers
Update README
Add fetch-world to README
Update README
Set NPROC to 1 by default

There is a strange issue on one of my machines where the build errors
out every now and then with NPROC > 1.  Default to 1 until we fix this.
Add debugging section in README
Busybox depends on kernel_headers
Update TODO
Update README - we don't need a multilib host
headers_install does not install all the required kernel headers

Simply do a cp for now.
Remove kernel_headers package

We don't need this currently, the cross compiler we use has its own
set of kernel headers.

When we compile musl from source we can revisit this.
Bump up NPROC to 4
Add kernel rebuilding instructions in README
Don't install the pre-formatted man-page
