cd $SRC/gnu && make depend

# update compiler tools
cd $SRC/gnu/usr.bin/binutils && make
cd ../gas.new && make
cd ../ld.new && make
cd ../egcs && make

# (you may want to copy the old a.out tools here, just in case)
cd $SRC/gnu/usr.bin/binutils && make install

# You may need this:
### cd $SRC/gnu/lib/libbfd && make

# now building ELF natively

# update include files and base libraries
cd $SRC && make includes
cd $SRC/lib/csu && make && make install

# finish the build
cd $SRC/gnu/lib && make && make install
