SHARED_MODE patch for gcc

[Egon Kocjan <egon at krul dot ath dot cx>]

Hello,

I build my software with crosstool's configuration glibc 2.2.2 & gcc 
4.1.1 to get portable c++ linux binaries. I have modified crosstool 
slightly, so it is possible to build a version of g++, which links 
dynamically to glibc related libraries but links libgcc & libstdc++ 
statically. Maybe the patch is of general interest, so I am submitting 
it here. To use the new functionality, put 
GCC_SHARED_MODE=--disable-shared in the configuration. Hacks like 
http://www.trilithium.com/johan/2005/06/static-libstdc/ can now be avoided.
