Add support for Arch Linux

[khughitt]

Greetings!

I put together a PR to extend sysreqsdb to support Arch Linux and its derivatives that use PKGBUILD files.

Few quick notes:

• In Arch, most libraries include their development headers, which is why you won't see any xx-devel packages.
• Some of the packages (e.g. bowtie2) are part of a widely-used community repo (AUR). They use the same PKGBUILD format as normal arch packages though and often packages that start out on the community repo end up migrating to the officially-maintained core/extra repos.
• I'm pretty sure 99% of the arch dependencies added should refer to the correct package and work as-expected. I did not test all of them, however, so it's possible there are some invalid ones as well. If users flag these though, I/others can fix the issues as they arise.

Thanks for your work on this useful package!

Cheers,
Keith

Thanks! This is awesome, and I'll be happy to merge it.

Two issues. One, the JSON format is changing, to facilitate automatic checks, and to make the web app that does the matching simpler. See the V2 branch. We can still merge this now, and then add the Arch Linux entries to the V2 branch later.

Second, would you be interested adding an Arch Linux Docker builder at https://github.com/r-hub/rhub-linux-builders?

Hi Gabor,

Sounds good -- I'll check out the v2 branch and update the JSON files there when I have the chance.
I was already planning on adding an Arch Dockerfile to the builder repo. I'll look into that now.. :)

Gonna modify changes for this PR to use gcc instead of clang since gcc is used by default.

Thanks! One important and 2 less important comments.

Minor thing, but indentation is wrong here.

[gaborcsardi]

Indentation.

This seems to be a typo here.

[khughitt]

Thanks for catching those! Should be fixed now..

Deployed, seems to work well: https://sysreqs.r-hub.io/pkg/igraph/linux-x86_64-arch-gcc

["gmp","libxml2"]

Sounds good! Just let me know if you notice any issues down the road.
