What didn't work? Boot? What happened?

Use the latest.

Just build the kernel and copy to /boot. Then update grub.cfg. Do
*not* change the headers. They need to be the same as used for building
glibc. The is no need to update gcc or glibc.

Thank you Bruce,
What happened was, that the boot started, but ended in kernel panic, then
the screen scrolled on very fast, obscuring what exactly happened.
If I understand you right, I can just rebuild the kernel, copy the files to
/boot and then update GRUB, so I think I will go for that solution.
