I don't get that as an error.  I get that it is not found, but as a nonfatal 
condition.
On a quick look it appears if you had libunwind installed there would be a more 
careful check for libdw.
That library is a part of elfutils that LFS doesn't install.
You could try -Dlibdw=disabled on the meson command.  You could try 
-Dlibunwind=disabled.
You could also do a complete install of elfutils and you would then have libdw 
(the dw is for Dwarf, the debugging symbol format).
