exclude feature for psyclone

[schreiberx]

Salut Sergi,
This is a simple additional feature where one can use the environment variable PSYCLONE_EXCLUDE_FILES to provide a comma separated list of files that shouldn't be processed with psyclone.
We could also tweak the build system, but in cases such as NEMO that's more challenging, hence this option.
Cheers,
Martin

We already have:

but perhaps also exposing this as an environment variable is valuable?

I think I should rename PSYCLONE_EXCLUDE_FILES to PSYCLONEFC_EXCLUDE_FILES (with FC) at the end because this is FC specific.
What do you think?

PS: In case this was unclear, the environment variable I'm proposing would never call any psyclone transformation, but would just execute the compiler.
