compile glibc 2.0: what are the object files

Hi,

I'm trying to compile glibc 2.0. In the documents it states:
"...The GNU C Library cannot be compiled in the source directory.  You must
build it in a separate build directory.  For example, if you have
unpacked the GNU C Library sources in `/src/gnu/glibc-VERSION', create
a directory `/src/gnu/glibc-build' to put the object files in.  This
allows removing the whole build directory in case an error occurs,
which is the safest way to get a fresh start and should always be done.

   From your object directory, run the shell script `configure' located
at the top level of the source tree.  In the scenario above, you'd type

     $ ../glibc-VERSION/configure ARGS..."

So it says "create
a directory `/src/gnu/glibc-build' to put the object files in".

But what object files do I place in glibc-build?

I downloaded the source from:
git clone git://sourceware.org/git/glibc.git

I'm on Centos 5.3.

Thank you,
Victor
