Under the radare

Hi folks,

I think now it is safe for the radare FreeBSD port maintainer to update the version as the 3.0.1 release is out.

At the moment, focus are into LLVM 8 for OpenBSD and especially FreeBSD.
For the OpenBSD build, disabling retguard and stack protector features seems to be used, to avoid large creation of their ELF sections and not be able to launch the executables. For FreeBSD, time to switch to the new 13th branch :-)

These days, I did a lot of golang professionally and discovered golangci-lint existence from one Dublin meetups contacts and was able to compare with more known gometalinter. The former might be appreciated from mid-size code due to its faster performance. Also able to highlight the "faulty" code. I recommend.
