Reorder configure script macros:

- Check for a compiler before looking for libraries or header files.
- Initialize automake before calling other AM_ macros.
- Disable libtool shared libraries by default.
- Remove checks for unused C++, Fortran, and Java compilers.
- Remove redundant AC_CANONICAL_HOST; called by AC_PROG_LIBTOOL.
