[Dont merge] test intarna rebuild

[martin-raden]

• I have read the guidelines for bioconda recipes.
• This PR adds a new recipe.
• AFAIK, this recipe is directly relevant to the biological sciences (otherwise, please submit to the more general purpose conda-forge channel).
• This PR updates an existing recipe.
• This PR does something else (explain below).

this PR tests why the intarna (re)build is broken...

Uaks.. should it be that easy??

[martin-raden]

Was about to ask what has changed in the build system, since this is not working anymore... we will see!
Thanks for joining @bgruening !

We are using GCC7 now and are about to drop the GCC from the container.

[martin-raden]

So do i need to rebuild viennarna again?

[martin-raden]

Mhh..

checking whether the C++ compiler works... no

configure: error: in `/opt/conda/conda-bld/intarna_1549658229757/work':

configure: error: C++ compiler cannot create executables

See `config.log' for more details

[bgruening]

Still the same error even with a new viennarna version :(

[martin-raden]

HI @bgruening
thanks for joining, was a mix of new cxx compiler and hard coded gxx in build.sh
