gcc and libstdc++-V3 build later

[Bill Cunningham]

I have bee looking at the LFS project. www.linuxfromscratch.org and I 
find their instructions a bit difficult. But at one point there is a gcc 
compiler compiled and installed with the --disable-libstdcxx option. 
Later, you are supposed to go back to your build directory and install 
libstdc++. I am not asking anyone to go to linuxfromscratch and 
investigate it so I will explain as much as possible as I believe I need 
too.

     This is compiling a "fake"cross compiler. Since everything is 
compiled from scratch, C++ libraries do not exist at the time of the 
first compilation. After glibc is built and installed, you go back to 
gcc and compile the libstdcxx libraries of gcc. Exactly how is that 
done? Am I off somewhere? The LFS documents I find to be a bit "unclear".
