I suggest not building zlib as a target library unless libgcj is also 
being built as a target library, given that there should be no need to 
built it as a target library in isolation.

It can be useful to build even GCC's target libraries when not building 
GCC (for example, rebuilding them with different optimization options 
using an installed compiler) - for libraries that don't use the host-side 
tm.h (all except libgcc and libobjc, I think), this is practical.
