It worked perfectly for me just now when I rechecked it. What version
of sed are you using? I'm using sed-4.2.1 from LFS 7.0.
One of the objectives of LFS/BLFS is to teach new concepts. I like to
add the -r switch to the book when it is useful to do that.
Note that the book has:
find -name Makefile -exec \
sed -ir -e '/^LIBRARYNAME/a SHARED_LIBRARY = 1' \
-e 's#BUILD_ARCHIVE :*= 1#NO_&#' \
-e '/^USEDLIBS/s# ([A-Za-z]*).a# -l\1#g' \
-e 's#^USEDLIBS#LDFLAGS#' {} \;
Did you miss the first backslash?
To be consistent, I probably should move the && on the configure line
above the 'find' to the same column as the rest of the segment.
