Changed the versioning of sci-chemistry/nwchem to use the package patchlevel versus the ebuild revision properly. Compilation without MPI support tested and corrected. Options added to compile with OpenMP, to compile the MRCC module, and to build against system BLAS.

Package-Manager: portage-2.2.11-r1
sci-mathematics/giac: Ebuild fix

FLTK paths added to CPPFLAGS and LDFLAGS.
The code invokes fltk-config, which breaks crosscompileability.
sci-mathematics/giac: Ebuild improvement

Added PAX-checks and exception for MPROTECT
