you're confusing the libs

the shared libs that are part of binutils are used by the host to generate 
code for the target, they are not for use by the target at runtime

ok ?  i just told you how to make it work ... make sure ld.so can find them at 
runtime and it doesnt matter where they are

*shrug* same sort of benefit you get from using shared libs versus static 
libs ... each binary is smaller, the shared libs are shared at runtime thus 
using less memory, etc...

shared libs are pretty well tested ... we've always used them in Gentoo and i 
have yet to see a bug that was caused by shared libs
