determine values like Fortran alignment (which can only be determined by running a program) when cross-compiling. By providing cache values, the programs will not be run at all, and life will be good. Also clean up some macro interfaces so that they are a bit easier to use, at the cost of horrid internals ;). This commit was SVN r8684.
