Not very different at all, except that you don't need to move
the compiler et al to the place where you have headers and
libraries. But I'd rather compare the suggested --sysroot to
--with-sysroot; they should behave the same.
This is useful for cross-compiling, where you have different
projects/products and where you've put all headers and libraries
somewhere that's to be copied to the target (you supposedly
don't want to install a different compiler for each). Moving
the installed compiler is different.
