To clarify: you mean this part:
cd glibc-2.20
patch -Np1 -i ../glibc-2.20-fhs-1.patch
mkdir ../glibc-build
cd ../glibc-build
echo "CFLAGS += -march=i486 -mtune=i686 -Os -pipe" > configparms
../glibc-2.20/configure --prefix=/usr --libexecdir=/usr/lib/glibc --disable-profile --enable-kernel=3.8.13 --enable-obsolete-rpc
find . -name config.make -type f -exec sed -i 's/-O2/ /g' {} \;
make
touch /etc/ld.so.conf
make install
Is that correct?
From what i understand, that file you linked is a build log for old tinycore from another environment (thus typical cross-compilation activity of first building compiler that can compile to needed target and then using it). I can get sources from the same location
Trying it out now
