Don't build shared libraries twice for `make world'. This reduces

`make world' times by about 10%.  Use a new `bootstrap-libraries'
target to build just enough (static) libraries to bootstrap the
tools, and delay building of shared libraries until all the tools
have been built.

Fixed `/usr/bin/make world'.  The version of `make' that we buildis
nand use is named "make", not ${MAKE}.
