Ref:
Linux From Scratch - Version SVN-20181029
Chapter 5. Constructing a Temporary System
5.5. GCC-8.2.0 - Pass 1
Using the latest script to update the dynamic linker results in gcc failing to
build.
Using a previous script fixes the problem.
Details below.

John
----------
This script:
for file in gcc/config/{linux,i386/linux{,64}}.h
do
cp -uv $file{,.orig}
sed -e 's@/lib\(64\)\?\(32\)\?/ld@/tools&@g' \
-e 's@/usr@/tools@g' $file.orig > $file
echo '
#undef STANDARD_STARTFILE_PREFIX_1
#undef STANDARD_STARTFILE_PREFIX_2
#define STANDARD_STARTFILE_PREFIX_1 "/tools/lib/"
#define STANDARD_STARTFILE_PREFIX_2 ""' >> $file
touch $file.orig
done
results in:

This script works:
for file in $(find gcc/config -name linux64.h -o -name linux.h)
do
cp $file $file.orig
sed -e 's@/lib\(64\)\?\(32\)\?/ld@/tools&@g' -e 's@/usr@/tools@g' $file.orig
> $file
echo '

#define STANDARD_STARTFILE_PREFIX_2 ""' >> $file
touch $file.orig
done
