- remove the old LGPL license headers from all files in Spack
- add SPDX headers to all files
- core and most packages are (Apache-2.0 OR MIT)
- a very small number of remaining packages are LGPL-2.1-only
When building eospac with %clang, spack's Fortran compiler wrapper is called
'flang', which is rejected by the eospac build system..Allow compilation with
%clang by patching the eospac build system.
My testing only covers %clang where flang is actually gfortran. However, this
patch only registers 'flang' as a known Fortran compiler and does not set any
flags or options that are compiler specific.
