include gcov in linux-64 toolchain

[loriab]

My thanks to the conda-build devs for the fantastic upgrade of compiler packages in particular and cb3 in general.

The only thing I've noticed to be missing is the gcov executable, though it looks (below) like the library and headers are present. If this wasn't deliberate, I'd petition for its eventual inclusion, as it'd be very handy for producing coverage reports from conda-builds.

Thanks @loriab this is probably the nicest bug report I've ever been assigned!

I'll take a look when I can. Am a bit snowed under ATM. @csoja there are a few other compiler issues we should look to fix too. Maybe a tracking bug would be good?

[loriab]

Thanks, @mingwandroid, "eventually" would be great. I mainly wanted to get this on the radar for the next time the compiler packages come up for revision.

[loriab]

Thanks so much! I look forward to the next compiler build.
