Add -frecord-gcc-switches for GNU Fortran so the compiler command line (including the optimisation level) is embedded in the njoy executable. This allows the build configuration to be inspected after the fact, e.g. with `readelf -p .GCC.command.line njoy`, making it easy to detect an accidental unoptimised (-O0) build. The option is guarded to GNU Fortran and is a no-op for other compilers.

Thanks for making NJOY and considering this PR
