Try flag -fcheck=all

[weslleyspereira]

Fix #512 using @jabl (#339) and @mgates (#512 (comment)) suggestions.

Uses a flag LAPACK_FORTRAN_STRLEN_END in CBLAS and LAPACKE.

Maybe I shall also:

• update make.inc.* with the new flag (I just used LAPACK_FORTRAN_STRLEN_END as set by default)
  ?? - [ ] change all methods in LAPACKE/include/lapack.h

[jabl]

Note that at least for GFortran (since version 8), Intel Fortran, and I believe the new LLVM Fortran compiler (flang, previously f18) use size_t for the hidden character length argument, not unsigned int.

[weslleyspereira]

All builds shall pass with this last commit. I defined LAPACK_FORTRAN_STRLEN_END by default following @mgates3 comments in #512 and LAPACK++ convention.

Should we (maybe I) change all methods in LAPACKE/include/lapack.h to use the new flag LAPACK_FORTRAN_STRLEN_END ?
I think not for now, and maybe in a separate PR. My main objective here is to allow for the use of -fcheck=all.
