build: Use caching for Fortran values in configure. * configure.ac: Rename ax_blas_integer_size to ax_cv_blas_integer_size. * octave_blas_f77_func.m4: Use AC_CACHE_CHECK macro for Fortran values. Rename values from "ax_blas_..." to "ax_cv_blas_..." to comply with requirement for "_cv_" in configure cache naming.
