Escape file write expansion, and build up lists. 

Escaped the @var@ in the file writes - this was being expanded at file
write and so not causing a reconfigure at the right time. I also took
care of build up lists of lists in the variables, especially important
for things like MPI_EXTRA_LIBRARY. Added some error checking, and use
the tmp_dir for initial cache file.
