524	Update for zlib and bzip2 installation instructions	gerard@…	lfs-book@…	"From Zack Winkles:

10. Build proper bzip2 libraries. We build the correct libbz2.so, as the
   Makefile adds -fPIC by itself, but then we simply run make, which adds
   all this PIC code into a static libbz2.a, which is completely
   unnecessary and unoptimal. In doing this, we slow down anything that
   uses libbz2.a by 20%. The ONLY thing needed to build a proper libbz2.a
   and libbz2.so is to make clean right after make -f Makefile-libbz2_so.
   The make clean leaves bzip2-shared and libbz2.so* intact, so there is
   no harm, only gain.

11. Build proper zlib libraries. The reasoning behind this is the exact
   same as that of libbz2, but the procedure is a bit more involved. The
   following commands do what we need:
        CFLAGS=""$CFLAGS -fPIC"" ./configure --prefix=/usr --shared
        make
        make install
        make clean
        ./configure --prefix=/usr
        make
        make install"	defect	closed	high		Book	CVS	normal	fixed
