Alex Crichton 3cf0b9bd11 mk: Don't install host rlibs
You rarely want to statically link against librustc and friends, so there's no
real reason to install the rlib version of these libraries, especially because
the rlibs are massive.

# It requires the following variables to be set:

# PREPARE_HOST - the host triple
# PREPARE_TARGETS - the target triples, space separated
# PREPARE_DEST_DIR - the directory to put the image
