# m4
tar xjf src/m4-*
cd m4-*
./configure\
    --prefix=$PREFIX
make clean && make -j4 && make install-strip
cd $WORK
rm -fr m4-*

# autoconf
tar xjf src/autoconf-2*
cd autoconf-2*

    --prefix=$PREFIX\
    --disable-debug
make clean && make -j4 && make install-strip
cd $WORK
rm -fr autoconf-2*

# automake
tar xjf src/automake-*
cd automake-*
./configure\
    --prefix=$PREFIX
    --disable-debug
make clean && make -j4 && make install-strip
cd $WORK
rm -fr automake-*

# libtool
tar xjf src/libtool-*
cd libtool-*
./configure\
    --prefix=$PREFIX
make clean && make -j4 && make install-strip
cd $WORK
rm -fr libtool-*

I believe the "mkdir src" inside the if should be "mkdir $WORK/src". Other fixes are possible.
