The most important thing is that the kernel headers to which glibc was 
linked remain in place. Once the whole system is built, there is no 
problem running a kernel with a later version as long as you leave the 
'old' headers in /usr/include.

Here are your options:
1) Continue with chapter 6 as is. When you've finished, build the new 
kernel before rebooting.
2) Start chapter 6 again using the new kernel headers. The tools you 
have (using the old kernel headers) will work fine.
3) Use LFS-5.1 The tools you have _should_ still work (I'm sticking my 
neck out here because I haven't tried this, and 5.1 was only released a 
day or two ago)

If it were my system I'd go for the adventurous option 3).
