scripts: check for, and warn about an unset CT_PREFIX_DIR

The user shall provide a directory to install the toolchain into.
If he/she does not, this is an error, and shall be detected properly,
rather than relying on failure down the road.

Thanks to "Pedro I. Sanchez" <psanchez@colcan.ca> for pointing out
the issue:

     4 # If we're in CT_LIB_DIR, then CT_LIB_DIR == CT_TOP_DIR, and we can update those

     5 # scripts for later inclusion mainline. If CT_LIB_DIR != CT_TOP_DIR, then those

     6 # scripts are downloaded only for use in CT_TOP_DIR.
