Reference-LAPACK PR 445, fixing their issue 263

from Reference-LAPACK PR 438

as explained by serguei-patchkovskii in Reference-LAPACK/lapack#438 (comment) , passing in an index of 1 instead of N leads to a standards violation accessing matrix A in SLASET, i.e. undefined behavior

Based on how the surrounding functions in lapack.h are handling the
parameters, particularly the ?ggsv?3-variants of the affected functions

Fix various wrong calls to SLASET/DLASET in the EIG part of the LAPACK testsuite

* Fix misnaming of LAPACK_?ggsvp and ?ggsvd function prototypes as LAPACKE_

* Drop the LAPACKE matrix_layout parameter from the argument lists, change ints to pointers and add missing work arguments.

Fix argument in SLASET call to zero S

fixes #1859 in accordance with https://github.com/LAPACK-Reference/issue/296

for #1811

The problem is that OpenBLAS sets the LAPACKE_LIB and the TMGLIB to the
same object and uses the `ar` feature to update the archive file. If the
underlying filesystem does not have sub-second timestamp resolution and
the system is fast enough (or `ccache` is used), the timestamp of the
builds which should be added to the previously generated archive is the
same as the archive file itself and therefore `make` does not update the
archive.

Since OpenBLAS takes care to not run the different targets updating the
archive in parallel, the easiest solution is to declare the respective
targets `.PHONY`, forcing `make` to always update them.

This could cause spurious "parameter has an illegal value" errors in DSYEVR and related routines, see https://github.com/Reference-LAPACK/lapack/issues/262
