The ~300 line bash script in toybox that builds bootable Linux systems
for a dozen-ish targets can use a vanilla kernel, but the binaries I
ship are built from a kernel with these patches:

https://github.com/landley/toybox/blob/master/scripts/mkroot.sh
https://landley.net/toybox/downloads/binaries/mkroot/0.8.9/

I've posted each patch to the list already, but here they are together
and updated for 6.2:

1) let LLVM build normally without telling Linux on the command line
This way I can mix CROSS_COMPILE=$ARCH-unknown-linux-cross- without
having to care that some are llvm and some are gcc.

2) don't require an extra dependency to build x86-64 no other target needs.

3) Make CONFIG_DEVTMPFS_MOUNT work in initramfs. That way having
the kernel build archive up a directory into a cpio.gz as a normal
user doesn't leave me without a /dev/console and thus init running
with stdin/stderr/stdout closed.

4) Replace the only user of bc with c. (Another package dependency
with only one user.)

5) Fix rootfstype=tmpfs in initramfs. (A thinko I made in 2013 which
nobody else has bothered to fix for a decade now.)

It's nice to see a diffstat of the whole series to at least get an idea
of who might merge the series.

Who were you thinking might merge the series?  I was only cc'ed on two
of them, I think.

There is no "Previously:" changelog tag.  Please use plain old "Link:".

Also, "See https://..." after the "^---$" will get chopped off.  It
might be helpful to includes this also as a Link: tag.
