Improved openifs block

[omula]

Hi,

I am trying to make openifs easyblock working with newer version and I've realised that FCM is like EasyBuild and that they provide several configurations to compile the model.

Which would be the best way to improve the easyblock? You can have a look to my current attempt now in https://github.com/omula/easybuild-easyblocks/tree/develop-openifs

In order to make it work I had to add the -convert big_endian to the flags. Would you leave it as it is right now?

Cheers,
Oriol

why the noopt?

@omula: ping?

[omula]

@boegel: I have tested the easyblock with the next OpenIFS release 40r1 and it works.

@omula: is there a PR for an updated OpenIFS easyconfig file?
