- Update to version 9.500.2:
* expanded solve() with solve_opts::likely_sympd to indicate
that the given matrix is likely positive definite
* more robust automatic detection of positive definite matrices
by solve() and inv()
* faster handling of sparse submatrices
* expanded eigs_sym() to print a warning if the given matrix is
not symmetric
* extended LAPACK function prototypes to follow Fortran passing
conventions for so-called "hidden arguments", in order to
address GCC Bug 90329;
* to use previous LAPACK function prototypes without the "hidden
arguments", #define ARMA_DONT_USE_FORTRAN_HIDDEN_ARGS before

(PATCH-FEATURE-OPENSUSE for now, but in discussions with
upstream to have this included).
