You can - and to answer the original question about rebuilding - look at 
something like the "mach" tool (not to be confused with mach the OS).

Loading times are more about link order than anything else. Tools like
gprof can help compute the optimal link order for binaries. Also fixing
up the library fixups can improve performance - and that is work that
has been done in gtk for example.
