Answer 1

got the fix, i had to change the location of default dynamic linker of gcc to use the one installed in /tools. The following step on page 34 was skipped:

for file in $(find gcc/config -name linux64.h -o -name linux.h -o -name sysv4.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
