compilers portgroup: add option for gcc5

[ryandesign (Ryan Carsten Schmidt)]

The compilers portgroup needs to add an option for gcc5, and in the future gcc6.

This points out a defect in the portgroup, in which the gcc_versions variable assumes the first digit of the version number is "4", and similarly that the clang_versions variable assumes the first digit is "3".

[ryandesign (Ryan Carsten Schmidt)]

Also, please add clang 3.6.

[seanfarley (Sean Farley)]

Yep, agreed.

Here's a braindead patch to support this. Any thoughts?

Can't there be just a single block that deals with all versions of gcc?

[seanfarley (Sean Farley)]

Thanks for the patch. I will really try to look at this today.

I assume because the logic of converting '49' -> '4.9' is annoying :-) I've made it one block and will push after running some tests.

Pushed as r136118.

You probably need to make corresponding changes in the openmpi-* ports. For example, port install arrack +gcc5 +openmpi won't work currently. Should I file a separate ticket for that?

I was waiting on #47541 to complete, then I'd copy Eric's work into openmpi :-)
